Vybrant™ Phagocytosis Assay Kit (Invitrogen™)

The Vybrant® Phagocytosis Assay Kit provides a way for researchers to observe and quantitate the process of phagocytosis in human polynuclear cells and mouse macrophages by following the internalization of a foreign particle—in this case killed E. coli (K-12 strain) cells that have been labeled with the fluorescent dye fluorescein. In addition to the lyophilized E. coli BioParticles® component, the kit contains a trypan blue solution (to quench the fluorescence from particles that were not internalized) as well as step-by-step instructions for performing this phagocytosis assay in a fluorescence microplate reader. The methodology used with this kit has been developed using an adherent murine macrophage cell line (J774); however, by modifying the cell culture conditions, researchers can adapt this phagocytosis assay to other adherent cell lines.

Click-iT™ TUNEL Alexa Fluor™ 647 Imaging Assay, for microscopy & HCS (Invitrogen™)

The Click-iT® TUNEL Alexa Fluor® 647 Imaging Assay utilizes a dUTP modified with an alkyne, a small, bio-orthogonal functional group that enables the nucleotide to be more readily incorporated by TdT than other modified nucleotides, including BrdUTP, biotin-dUTP or fluorescein-dUTP. Detection is based on a click reaction, a copper (I) catalyzed reaction between an azide and alkyne. Click chemistry fills the void when methods such as direct labeling or the use of antibodies are not efficient. The small size of the detection reagent, an Alexa Fluor® azide (MW <~1000) compared to that of an antibody (MW ~150,000) enables facile penetration of complex samples with only mild fixation and permeabilization required.

Compared to other assays using one of the other modified nucleotides, the Click-iT® TUNEL assay is able to detect a higher percentage of apoptotic cells under identical conditions. The assay is also fast and is complete within 2 hours. Furthermore, the Click-iT® TUNEL assay allows multiplexing with surface and intracellular biomarker detection.

eBioscience™ Mouse Regulatory T Cell Staining Kit #1 (Invitrogen™)

The FJK-16s antibody reacts with mouse/rat Foxp3 also known as FORKHEAD BOX P3, SCURFIN, and JM2; cross reactivity of this antibody to other proteins has not been determined. Foxp3 a 49-55 kDa protein, is a member of the forkhead/winged-helix family of transcriptional regulators, and was identified as the gene defective in ‘scurfy’ (sf) mice. Constitutive high expression of Foxp3 mRNA has been shown in CD4+CD25+ regulatory T cells (Treg cells), and ectopic expression of Foxp3 in CD4+CD25- cells imparts a Treg phenotype in these cells.

Immunoblotting with FJK-16s antibody has mapped the epitope to amino acids 75-125 of the mouse Foxp3 protein. In the human, this region has been shown to be alternatively spliced at the mRNA level. Both the alternatively-spliced and non-spliced isoforms are present in the CD4+CD25+ subset of lymphocytes. Preliminary RT-PCR experiments have not revealed this alternatively-spliced isoform in mouse splenocytes, suggesting different gene regulation in the mouse and human.

Intracellular staining of mouse splenocytes with FJK-16s using the mouse Foxp3 staining sets and protocol reveals approximately 2% of total splenocytes in the C57Bl/6 strain and approximately 3-5% in the BALB/c mouse strain. Multicolor flow cytometric analysis demonstrates approximately 90% of the CD4+CD25+ cells and 4% of the CD4+CD25- cells staining with FJK-16s. B220+, CD11b+, CD11c+, and Ly6G/Gr-1+ cells do not show significant co-staining with FJK-16s. These data are consistent with a recent report which follows expression of Foxp3 using a GFP knock-in (Fontenot et al, 2005).

FJK-16s cross-reacts with rat Foxp3 This has been demonstrated by intracellular staining of Foxp3 and flow cytometry of rat splenocytes using the same method and reagents as used for mouse tissue. Please note that the CD4 and CD25 antibodies included in this kit only recognize the mouse antigens. For staining rat tissue, please use (CD4 FITC cat. 11-0040 and CD25 APC cat. 17-0390)

Click-iT™ EdU Cell Proliferation Kit for Imaging, Alexa Fluor™ 488 dye (Invitrogen™)

The Click-iT EdU Cell Proliferation Kit for Imaging is a superior alternative to traditional proliferation assays that is optimized for fluorescence microscopy applications. In this assay the modified thymidine analogue EdU is efficiently incorporated into newly synthesized DNA and fluorescently labeled with a bright, photostable Alexa Fluor® dye in a fast, highly-specific click reaction. This fluorescent labeling of proliferating cells is accurate and compatible with antibody methods due to the mild click protocol.

• Simple—works the first time, every time, in less time
• Efficient—no denaturation steps or harsh treatment required
• Content-rich results—better preservation of cell morphology, antigen structure, and DNA integrity
• Consistent—not dependent on variable antibody lots for detection

The most accurate proliferation-detection methods are based on the incorporation and measurement of nucleoside analogues in newly synthesized DNA, with bromodeoxyuridine (BrdU) a commonly used analogue. BrdU-labeled DNA is quantitated using anti-BrdU antibodies following DNA denaturation by harsh methods (HCl, heat, or enzymes) to expose the BrdU molecules. This step is time consuming and difficult to perform consistently. The harsh treatment can also adversely effect sample integrity and quality, which makes co-staining with other antibodies challenging.

Superior Proliferation Methodology
The Click-iT EdU Cell Proliferation Kit for Imaging provides a superior alternative to BrdU assays for measuring cell proliferation. EdU (5-ethynyl-2'-deoxyuridine) is a nucleoside analog of thymidine and is incorporated into DNA during active DNA synthesis. With Click-iT® EdU, mild fixation and detergent permeabilization is sufficient for the small molecule-based Click-iT® EdU detection reagent to gain access to the DNA. As a consequence, the Click-iT® EdU imaging kit is not only easy to use, but more accurate and compatible with cell cycle analysis and other intracellular or extracellular targets for truly content-rich results.

This kit is optimized for fluorescence microscopy applications; visit the Click-iT® technology area of our website for kits designed for high-content imaging, fluorescence microplate, or flow cytometry platforms.

Notes:
The Click-iT® assay can be used on cells in culture or in vivo following EdU administration by feeding or injection methods.
The Click-iT® assay can be used with BrdU in dual pulse experiments by using the anti-BrdU (clone MoBu-1) antibody, which does not cross react with EdU.
The Click-iT® technology is compatible with immunohistochemical, immunocytochemical, and fluorescent dyes that are fixation tolerant or designed for fixed cell labeling.

Image-iT™ LIVE Red Caspase-3 and -7 Detection Kit, for microscopy (Invitrogen™)

The Image-iT™ LIVE Red Caspase-3 and -7 Detection Kit employs a novel approach to detect active caspases that is based on a fluorescent inhibitor of caspases (FLICA™) methodology, essentially an affinity label. The reagent associates a fluoromethyl ketone (FMK) moiety, which can react covalently with a cysteine, with a caspase-specific amine acid sequence. For caspase-3 and -7, this recognition sequence is aspartic acid-glutamic acid-valine-aspartic acid (DEVD). A sulforhodamine group (SR) is attached as a reporter. The FLICA reagent is thought to interact with the enzymatic reactive center of an activated caspase via the recognition sequence, and then to attach covalently through the FMK moiety. The FLICA inhibitor is cell permeant and noncytotoxic. Unbound FLICA molecules diffuse out of the cell and are washed away; the remaining red-fluorescent signal is a direct measure of the amount of active caspase that was present at the time the inhibitor was added.

CellEvent™ Senescence Green Detection Kit (Invitrogen™)

The CellEvent Senescence Green Detection Kit consists of a fluorescent probe and optimized buffer that enable the image-based detection of senescent cells. The fluorescein-based probe contains two galactoside moieties, making it a target for β-galactosidase. Activation of β-galactosidase is commonly used as a biomarker for senescent cells. This hydrolase enzyme resides in lysosomes and converts β-galactosides into monosaccharides under acidic pH conditions. The enzymatically cleaved product is retained within the cell due to covalent binding of intracellular proteins and emits a fluorogenic signal that has absorption/emission maxima of 490/514 nm.

CellEvent Senescence Green Detection Kit features include:
• Reliable and quick fluorescent detection of senescent cells
• Greater sensitivity than traditional colorimetric x-gal
• Fluorescent signal is well retained and detected using standard Alexa Fluor 488/FITC filter sets
• Multiplex-enabled—fluorescent senescence probe can be multiplexed

Due to a limited replicative lifespan, normal cells enter cell cycle arrest, also known as cellular senescence. While in this senescent phase the cells remain metabolically active without undergoing cell death or division. They adopt a specific phenotypic that includes the appearance of multiple nuclei, increased vacuolization, expression of pH-dependent β-galactosidase, and morphological enlargement and extension. Senescence, through a variety of mechanisms, may play a role in tumor suppression, tumor progression, aging, and tissue repair.

Activation of β-galactosidase is commonly used as a biomarker for senescent cells. This hydrolase enzyme resides in lysosomes and converts β-galactosides into monosaccharides under acidic pH conditions. The activity is optimal at lysosomal pH 4, but conventional assays measure at pH 6. It has been shown that normalized β-galactosidase activity is twice as high in senescent cells as in pre-senescent cells regardless of the pH value used for testing.

A colorimetric substrate for β-galactosidase, 5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside (x-gal), has long been used to detect metabolic activity in cells in vitro. However, its use is limited due to inconsistent signal, length of assay, and inability to multiplex.

Therefore, we have developed a sensitive, fluorescent substrate for β-galactosidase that can be used for the detection of senescent cells. The CellEvent Senescence Green probe is a fluorescein-based reagent that contains two galactoside moieties, making it a specific target of β-galactosidase. The enzyme- cleaved product is retained within the cell due to covalent binding of intracellular proteins and emits a fluorogenic signal that has absorption/emission maxima of 490/514 nm.

The CellEvent Senescent Green Kit provides CellEvent Senescent Green probe and an optimized buffer for the detection of senescent cells in fixed samples. This probe can be multiplexed with other fluorescent reagents compatible with paraformaldehyde fixation.

Avoid the Harsh Treatments Associated with BrdU Method
Measuring changes to cell proliferation is a fundamental method for assessing cell health, determining genotoxicity, and evaluating anti-cancer drugs. The most accurate method of doing this is by directly measuring DNA synthesis. The traditional method utilizes the nucleoside analog BrdU (5-bromo-2'-deoxyuridine, a nucleoside analog of thymidine), which is incorporated into newly transcribed DNA. After incorporation the samples are treated with harsh methods (HCl, heat, or enzymes) to denature the DNA and expose the BrdU molecules to detection by anti-BrdU antibodies. However, the BrdU method to measure cell proliferation is time consuming and difficult to perform consistently. The harsh treatments necessary for this method can adversely affect sample integrity, cell morphology, image quality, and the ability to multiplex.

The Click-iT® Plus EdU assay measures the rate of new DNA synthesis based on incorporation of the nucleoside analog EdU into DNA. Detection is achieved through a catalyzed "click" reaction that is completed typically within 30 minutes. The click reaction uses bioorthogonal (biologically unique) moieties to fluorescently label proliferating cells, producing low backgrounds and high detection sensitivities. Because of the mild reaction conditions the Click-iT® Plus assays can accurately determine cell proliferation while preserving cell morphology, DNA integrity, antigen binding sites, and the fluorescent signal from GFP. Preservation of DNA integrity allows for DNA staining, including staining with dyes used for cell cycle analysis.

CaspGLOW™ Fluorescein Active Caspase-8 Staining Kit (Invitrogen™)

The CaspGLOW™ Fluorescein Active Caspase-8 Staining Kit contains all the reagents necessary to detect active caspase-8 in cells with high sensitivity. Fluorescein (FITC)-conjugated IETD-FMK, a specific inhibitor of caspase-8, is utilized in this assay for detection. This reagent is cell permeable, non-toxic and irreversibly binds to the active enzyme. Detection of the labeled cells can be determined by flow cytometry, fluorescent microscopy or a fluorescent plate reader.

The caspases constitute a family of aspartate-specific cysteine proteases that mediate a sequence of cleavage events. Recruitment of the inactive proenzyme to oligomerized receptors leads to caspase activation and autoproteolytic cleavage. These active enzymes can then cleave other caspases, thereby generating a caspase signaling cascade that leads to a form of programmed cell death termed apoptosis.

Caspase-8, which is also known as FLICE, MACHalpha1, and Mch5, cleaves its substrates at the C-terminal aspartic acid residue of the motif Asp-X-X-Asp. Eight isoforms of caspase-8 exist, of which caspase-8/a and 8/b are the predominant forms. Upon stimulation of death receptors such as CD95/APO-1/Fas, TRAIL-R1, TRAIL-R2, TNFR1, and TRAMP, caspase-8 is recruited to the death-inducing signaling complex (DISC). Subsequent dimerization leads to caspase-8 activation via autocatalytic cleavage, which leads to the formation of a 12-kDa prodomain and a 43-kDa intermediate fragment that is further cleaved to produce 26-kDa and 18-kDa active enzymes. As an initiator caspase, this enzyme initiates a caspase signaling cascade that results in apoptosis. Substrates of caspase-8 include caspases-3 and -7, as well as the pro-apoptotic Bcl-2 family member Bid. In addition to its role in cell death, caspase-8 has been linked to cell adhesion and motility.
