Story of BioTracking

Dr. Garth Sasser discovered pregnancy specific protein B (PSPB) from the placenta of cows. He developed a radioimmunoassay for the protein while he served as a professor at the University of Idaho, and was the first to show that a protein could be used as a blood-based test for pregnancy in ruminant animals.

BioTracking, LLC was established in 1992 for the development and marketing of a pregnancy-specific protein B (PSPB) test for pregnancy in cattle. The test was named BioPRYN®, with PRYN standing for “Pregnant Ruminant Yes No”. This technology was licensed by BioTracking from the University of Idaho and the assay was converted to an enzyme-linked immunosorbent assay (ELISA). The result was BioPRYN, an affordable blood-based pregnancy test for cattle.

BioPRYN products for sheep and goats later became available, as did BioPRYNwild, a conversion of the radioimmunoassay (RIA) test to an ELISA. BioPRYNes, a test of equine blood for estrone sulfate was established in 2008 as a pregnancy test.

BioTracking, under the management of the Sasser family and a team of skilled and knowledgeable staff, continues to build upon the tradition of rapid, friendly, and attentive service. The BioTracking research team is continuously working to make livestock pregnancy testing easier, more reliable and convenient, as the company strives for improved testing options that will benefit the livestock markets.
