HCP Quantification and Validation Products
- Amersham™ HCPQuant CHO ELISA and Amersham™ Anti-CHO HCP Antibody kits - Our products are designed to quantify and characterize host cell proteins in process-derived samples harvested from CHO supernatant and reduce the risk of unexpected host cell proteins during the transition from generic to specific HCP ELISAs. This results in helping you to maximize the efficiency of your HCP management strategy.
- DIBE™ HCP CHO kit: for validating HCP ELISAs
- Melanie™ coverage software: Analyze how well your HCP antibody covers all the HCPs in your sample.
