We offer the most comprehensive selection of monoclonal and polyclonal primary antibodies for academic and industrial researchers, but also clinical purposes (CE-IVD). We offer a big selection of primary antibodies raised in several species (rabbit, mouse, rat, goat, donkey, …) – even directly conjugated to fluorescent dyes (DyLight, FITC, Cy dyes,…), HRP, AP or biotin. Regardless the field of research you are working in our primary antibodies will support your experiments with well-characterized and consistent performance.

Our range of secondary antibodies has been carefully selected to provide optimum quality and flexibility. We offer a variety of purified conjugated (HRP, biotin, FITC, AP, DyLight and other dyes,…) or unconjugated secondary antibodies that can be used for fluorescent, colorimetric, and chemiluminescent detection of a primary antibody in a wide range of applications including Western Blotting, ELISA, immunofluorescence, immunohistochemistry, immunocytochemistry and flow cytometry.
For most secondaries, we offer a choice of whole IgG molecules, various isotypes, or F(ab’)2 fragments. We also offer the most comprehensive selection of secondary antibodies with respect to the species of origin (human, mice, goats, rats, rabbits, sheep, chickens, horses, guinea pigs and more).

Please contact our support team with any inquiries about our products. Our team is ready to help with finding a suitable antibody, experimental design or troubleshooting.


If you have an issue with any of our products, we can help you in two ways: PhD-level technical support and individual guarantee programs are both available. Our focus is to make your life as easy as possible.

Trial Sizes, Free Samples

As there are always special offers from our suppliers just contact us for more information on small “test” sizes or even free samples.

Custom Production

We can provide you with a bespoke project that fits your individual needs. Our team invests time and effort in your project: from when we advise on the project design until the final bleed is delivered and we help with optimization.
Moreover, a lot of our antibodies are available in small scale but also and bulk quantities.

Replace Santa Cruz Antibodies

Many Santa Cruz polyclonal antibodies were discontinued on December 31 2016. Avoid delays in your research by using our knowledge where and how to replace Santa Cruz antibodies e.g. with the most popular alternatives from Proteintech (Replacement list (PDF)).

Discontinued or Unsatisfying Antibody?

Having trouble searching for a discontinued antibody? Not happy with the antibody you’re using?  Avoid delays in your research. Find an alternative to any major antibody supplier by using our knowledge in antibody suppliers.

Optibodies™ – Antibodies for IHC

Optibodies™ are a range of optimized antibodies for markers which are clinically and diagnostically important. Research frequently necessitates a range of antibodies tailored to the specific needs of each individual project. In clinical perspective, antibodies must be specific with high affinity towards their epitopes, flexible to use, good LOT consistency and reliable. Optibody™ antibodies are carefully validated and fine-tuned with the needs of today’s clinical IHC laboratory. Optibodies™ are validated and optimized using NordiQC (Nordic immunohistochemical Quality Control) recommendations of control tissues and criteria.

ChIP Validated Antibodies

Chromatin immunoprecipitation (chromatin IP or ChIP) is an extremely challenging technique, and only antibodies of the highest quality will do. For an antibody to work in chromatin IP, it must be of high titer and it must be very specific, with no detection of non-target proteins. Most importantly, it must be able to recognize the target protein in its native chromatin-associated context after fixation. Active Motif specializes in manufacturing high-quality antibodies to histones, histone modifications and chromatin proteins and validating them for use in ChIP, as well as ChIP-Seq & ChIP-chip. In addition, their Epigenetic Services team offers ChIP Antibody Validation Services in which they will determine if your antibody is suitable for use in ChIP, ChIP-Seq or ChIP-chip.

To help make your ChIP even more successful, Active Motif offers its complete line of ChIP-IT® Express Kits for performing Chromatin IP, high-throughput ChIP, sequential ChIP and even RNA ChIP.
