Western Blot Kits

Western blot detection kits are used to demonstrate the reaction of HCP antibodies with the majority of HCPs present in a given cell line or purification process. Due to sensitivity limitations, however, coverage can only be estimated on upstream, harvest samples where HCPs are still within the sensitivity limitations of various staining methods.

Western blot detection kits provide limited predictive value in determining how the ELISA using that antibody will quantitatively react to the more limited array of HCPs in downstream samples.
