Animal Specific Assays and Cross-Reactivity

Offering a range of endocrine immunoassays for the analysis of animal samples.

The Quick Reference Matrix that can be downloaded here.

Researchers, endangered species experts, and veterinary surgeons throughout the world utilize Ansh Labs’ range of endocrine immunoassays for the analysis of animal samples. Plasma, serum, saliva, fecal extracts, tissue extracts, and samples from cell culture media are examples of the varied types of samples that have been analyzed using our assays in numerous applications and in a vast range of species. In addition to client publications and reports, we have also validated many of our immunoassays for various animal species as well as offering an array of species-specific assays.


Animal AMH kits from Ansh Labs utilize monoclonal antibodies carefully selected for high affinity and specificity for certain species. Where available, species–specific calibrators have been employed. Our assays have been optimized to not cross-react with other closely related analytes. The enhanced specificity and analytical sensitivity allow for greater detection of AMH at low concentrations. Ansh Labs also has species-specific kits for IGF-I, Activin B, Inhibin A, Inhibin B, and PAPP-A.


The Quick Reference Matrix that can be downloaded here is intended to give the reader a convenient overview of the immunoassays that have been tested for various animal applications. This information has been collated over many years, from a number of different sources, and indicates the suitability of the Ansh Labs’ assays for animal specimen analysis.

Unique studies done with Ansh Labs' kits

One of the best-known marine mammal parks worked with Ansh Labs to test several AMH antibodies and found a pair that worked perfectly for bottlenose dolphins.  This has helped them to implement breeding programs.

Another large exotic animal veterinarian validated our Canine AMH assay and found that it worked perfectly in big cats. As a result, an African group was able to test their lioness population to evaluate the animal’s ovarian functions.

We also hold the honor of having our assay used to test white rhinos, including the few remaining female northern white rhinos.
