If you are building antibody cocktails for flow cytometry applications, you can find the specific antibodies you need and appropriate color combinations at Antibodies for Flow Cytometry.
Our Alexa Fluor® secondary antibody conjugates and streptavidin conjugates set the standard for detection in the life science industry. Life Technologies’ anti-GFP antibody is the most commonly used secondary detection reagent for fluorescent proteins in fixed samples. We offer anti-dye, anti-hapten, and anti-tag antibodies that permit multicolor signal amplification in essentially any immunoassay format. To identify the best secondary antibody for your application, please try our secondary antibody selector tool.
Our Alexa Fluor® Zenon® kits permit you to combine multiple primary antibodies of the same species in the same sample, without having to prepare conjugates. Up to seven colors of Zenon® reagents have been used at the same time to detect samples in pathology assays and flow cytometry.
Life Technologies provides a complete selection of secondary detection reagents for use in signal amplification. Build your immunoassay kit or service using Tropix® chemiluminescence substrates, Amplex® Red fluorogenic horseradish peroxidase substrates, or standard colorimetric substrates.
Another very powerful enzymatic secondary detection technology is based on Tyramide Signal Amplification (TSA®). TSA® (PerkinElmer) is an enzyme-mediated detection method that utilizes the catalytic activity of horseradish peroxidase (HRP) to generate high-density labeling of a target protein or nucleic acid sequence in situ. We can custom-formulate these reagents and specially package them for direct inclusion in your kits or for use in your service.
More detailed information about our antibodies and secondary detection technologies is available on our product web pages.
We offer 24 different fluorescent labels for primary antibodies, secondary antibodies, anti-dye and anti-hapten antibodies, and streptavidin, including proprietary labels such as Alexa Fluor®, Texas Red®-X, and Pacific Blue™ dyes, which span the visible light spectrum from deep blue to near-infrared emission, generic fluorophores such as fluorescein and tetramethylrhodamine, R-phycoerythrin (RPE), allophycocyanin (APC), and PerCP. We also offer conjugates of biotin, DNP, digoxigenin, dansyl, and other haptens. We have more than 30 years experience in preparing custom antibody conjugates to match your instrument and optical specifications, which are optimized to meet your application-specific assay needs. We can also couple antibodies to gold particles, polystyrene microspheres and nanospheres, and magnetic particles for you.

Protein Detection and Quantitation
TC-FlAsH™ Expression Analysis Detection Kits
TC-FlAsH™ technology allows you or your customers to add a small tetracysteine tag to target proteins, which can then be isolated or detected rapidly in living cells, in vitro in solution, and in gels. This method is complementary to immunodetection methods, and does not require the use of an antibody. Licenses are available for use of the technology in contract research, and for inclusion of tetracysteine-labeled proteins in kits for resale, along with your choice of detection or isolation reagents.
