About Us

Biological Specialty Corporation (BSC) supplies the scientific community with human biologicals collected at our own FDA registered donor centers. Products include blood, plasmas and sera, as well as white blood cells, red blood cells, mother’s milk, urine, saliva, semen, cerebral spinal fluid, and various other human biologicals. Our donors are screened according to AABB guidelines and, with the exception of Cerebral Spinal Fluid, all of our products undergo the complete battery of FDA required infectious disease state tests. If you are in need of a matrix that is not listed in our catalog, we will make every effort to procure it for you.


Our Cell Isolation has become an invaluable resource to many of our customers. We isolate various lines from our white blood cell products using ficoll and negative selection. The cells can be shipped fresh or cryopreserved for later use.
