As you define your parameters the list of available kits matching your selection will appear in the...

FITC (fluorescein isothiocyanate) is a fluorochrome dye widely used as an antibody or other probe marker. FITC absorbs ultraviolet or blue light, exciting molecules which then emit a visible yellow-green light. When the excitation light is removed, the emission light ceases.

The attachment of fluorescent dyes to proteins and other biomolecules is a common strategy used to better understand protein structure and function. These fluorescent proteins can be used in a broad range of applications including immunochemistry, fluorescence in situ hybridization (FISH), cell...

Thermo Scientific DyLight microscale protein labeling kits contain NHS ester-activated derivatives of our high-performance DyLight dyes designed specifically for labeling small quantities of antibodies or proteins.

Green fluorescent protein (GFP) is a 27 kDa monomeric protein, isolated from the jellyfish Aequorea Victoria that auto-catalytically forms a fluorescent pigment. GFP is a versatile marker for monitoring physiological processes, visualizing protein localization, and detecting transgenic expression.

Biotin is a water-soluble B vitamin consisting of an ureido ring fused with a tetrahydrothiophene ring. Biotin is essential for all organisms, as it is involved in cell growth, the production of fatty acids, the metabolism of fats and amino acids, the citric acid cycle, the transfer of carbon...

Invitrogen Molecular Probes Pacific Blue dye is a bright blue-fluorescent dye optimally excited by the 405 nm line of the violet laser and with excitation/emission at 410/455 nm. Conjugates of this dye are strongly fluorescent even at neutral pH.

Pacific Orange dye is a bright orange-fluorescent dye optimally excited by the 405 nm line of the violet laser and with excitation/emission at 400/551 nm. Conjugates of this dye are strongly fluorescent even at neutral pH.

Invitrogen Alexa Fluor 568 dye is a bright, orange-fluorescent dye with excitation ideally suited for the 568 nm laser line on the Ar-Kr mixed-gas laser. For stable signal generation in imaging and flow cytometry, Alexa Fluor 568 dye is pH-insensitive over a wide molar range.

Invitrogen Alexa Fluor 680 dye is a bright, near-IR fluorescent dye with excitation ideally suited for the 633 nm laser line. For stable signal generation in imaging and flow cytometry, Alexa Fluor 680 dye is pH-insensitive over a wide molar range.

IgG primary antibodies are usually available only in small quantities, can be expensive, and are packaged with stabilizing proteins such as bovine serum albumin (BSA). These stabilizing proteins can interfere with the amine-reactive reagents used to covalently attach a fluorescent label.

Invitrogen Alexa Fluor 594 dye is a bright, red-fluorescent dye that can be excited using the 561nm or 594nm laser lines. For stable signal generation in imaging and flow cytometry, Alexa Fluor 594 dye is pH-insensitive over a wide molar range.

Alexa Fluor 750 dye is a bright, near-IR–fluorescent dye with excitation ideally suited for the 633 nm laser line or dye-pumped laser excitation. Alexa Fluor 750 dye is pH-insensitive over a wide molar range, helping ensure that you get stable signals in imaging and flow cytometry applications.
