Doing CHO HCP Assays?

Trust Your CHO HCP Assay to the Experts!

Superior sensitivity and specificity for CHO HCP detection

Cygnus has used proprietary technologies to obtain antibodies and develop robust assays that react to the most important HCPs, those that co-purify with your product. We evaluated antibodies for reactivity to individual HCPs using the conventional 2D Western blot and Antibody Affinity Extraction (AAE). AAE demonstrated the CHO HCP antibody is reactive to more than 1000 individual HCPs from conditioned media and cell lysates in both currently used CHO strains.

CHO Host Cell Protein ELISA Kit, 3G

 

  • The most sensitive CHO HCP ELISA kit: LOD~0.3 ng/ml, LOQ ~1 ng/ml
  • Based on antibodies with the broadest CHO HCP coverage and reactivity to those HCPs that persists through the downstream purification process
  • Supports multiple commercialized biologics
