Antibody Production and Services

ProSci Incorporated specializes in the production of affinity-purified peptide-specific polyclonal antibodies to novel antigens in fields such as HIV. To date, ProSci has an antibody catalog of over 30,000 antibodies. Many of the polyclonal research antibodies offered by ProSci are affinity-purified, which allows for the isolation of antibodies specific to the epitope of interest. As a result, ProSci's antibodies have the same specificity as monoclonal antibodies at a price below our competitors' polyclonal antibodies. In addition, ProSci offers a complete assortment of cell lysates, tissue lysates and peptides to complement the use of these antibodies.
