ProSci Inc. We specialize in the production of affinity-purified peptide-specific polyclonal antibodies to novel antigens in fields such as Apoptosis, HIV/Chemokine Receptors, Signal Transduction, Neurobiology and Immunology. To date, we have an antibody catalog of over 13,000 antibodies. Many of the polyclonal research antibodies offered by our company are affinity-purified, which allows for the isolation of antibodies specific to the epitope of interest. As a result, our antibodies have the same specificity as monoclonal antibodies at a price well below competitors' polyclonal antibodies. In addition, we offer a complete assortment of cell lysates, tissue lysates and peptides to complement the use of these antibodies
