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...
Get high quality cell viability results and instant time savings with PrestoBlue® Cell Viability Reagent. PrestoBlue® is a ready to use cell permeable resazurin-based solution that functions as a cell viability indicator by using the reducing power of living cells to quantitatively measure the...
Click-iT Plus EdU Cell Proliferation imaging kits have been optimized for fluorescence microscopy applications and are a superior alternative to traditional proliferation assays. In this assay the modified thymidine analogue EdU (5-ethynyl-2'-deoxyuridine, a nucleoside analog of thymidine) is...
Cell Proliferation Dye eFluor™ 670 is a red fluorescent dye that can be used to monitor individual cell divisions. This fluorescent dye binds to any cellular protein containing primary amines, and as cells divide, the dye is distributed equally between daughter cells that can be measured as...
In the Vybrant™ Cell Metabolic Assay Kit, nonfluorescent C12-resazurin is reduced to fluorescent C12-resorufin by viable cells; the resulting signal is proportional to the number of cells present. C12-resazurin has better cellular retention than alamarBlue™ dye and can be multiplexed with viability...
The HCS LIVE⁄DEAD® Green Kit measures cytotoxicity by high content analysis with the Image-iT® DEAD Green™ viability stain – a non-fluorescent and cell impermeant compound that exhibits a strong fluorescent enhancement upon binding to DNA.
The Amplex™ Red Hydrogen Peroxide/Peroxidase Assay Kit contains a sensitive, one-step assay that uses the Amplex™ Red reagent (10-acetyl-3,7-dihydroxyphenoxazine) to detect hydrogen peroxide (H2O2) or peroxidase activity.
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...
Human low-density lipoprotein (LDL) is large protein complex (∼500,000 Da) that binds to a specific receptor on the surface of vertebrate cells and delivers cholesterol via receptor-mediated endocytosis—our labeled LDL complexes are useful tools for studying this phenomenon.
Oregon Green 488 BAPTA-1, hexapotassium salt is a visible light—excitable calcium indicator. This water-soluble, salt form is useful for intracellular loading by microinjection, infusion from patch pipette or uptake induced by our Influx pinocytic cell-loading reagent (I-14402).
Carboxy-DCFDA can passively diffuse into cells and is colorless and nonfluorescent until the acetate groups are cleaved by intracellular esterases to yield the fluorescent fluorophore, 5-(and-6)-carboxy-2',7' -dichlorofluorescein. With a pKa of 4.8, this dye can be used as an acidic pH sensor.
The HCS LipidTOX™ Green phospholipidosis detection reagent was developed to characterize the potentially toxic side effects of compounds on lipid metabolism in mammalian cell lines. This reagent is easily detected by fluorescence microscopy or an HCS reader equipped with filters that can detect...
The cell-impermeant visible light—excitable, low affinity Ca2+ indicator, Oregon Green™ 488 BAPTA-6F, hexapotassium salt has a Kd for Ca2+ ∼3 μM and absorption/emission maxima ∼492/517 nm. Learn more about ion indicators including calcium, potassium, pH, and membrane potential indicators ›
XTT is used to assess cell viability as a function of redox potential. Actively respiring cells convert the water-soluble XTT to a water-soluble, orange colored formazan product. Unlike MTT, XTT does not require solubilization prior to quantitation, thereby reducing the assay time in many viability...
Labeled calcium indicators are molecules that exhibit an increase in fluorescence upon binding Ca2+. They have uses in many calcium signaling investigations, including measuring intracellular Ca2+, following Ca2+ influx and release, and multiphoton excitation imaging of Ca2+ in living tissues.

I'm trying to label my cells in suspension and track them over time by labeling with CFDA SE, but after labeling them they will no longer adhere to a surface (whereas unlabeled cells adhere well). I've tried to label at 10 and 20 µM. What is causing this?
