Cygnus Technologies has performed an antibody coverage bridging study between the F550 and F550-1 versions of their 3rd generation CHO ELISA kits by Antibody AffinityExtraction (AAE™) with host cell protein (HCP) detection by LC-MS (AAE-MS). The immunoreactivity between F550 and F550-1 antibodies against the CHO master antigen (CMA) HCPs was 97% and 97%, respectively. F550-1 … Continue reading Case Study: Bridging Anti-CHO Host Cell Protein Antibodies
