Purexa™ PrA mini - Fast Antibody Purification within 1 Minute

Oct 29, 2020

Purexa™ PrA mini is designed for rapid processing of small quantity of antibodies, especially at low titers. During elution, the first 0.5 mL was discarded. As is shown in the fitures, a majority of the antibody was eluted in the second 0.5 mL elution fraction, which had a concentration of 3.3 mg/mL and was corresponding to a recovery of 78%.
