Detection And Quality Control Of Host Proteins
Detection And Quality Control Of Host Proteins
Host proteins (HCP) form a major part of the process-related impurities in the production of biologics. The amount of residual HCP in a pharmaceutical product is often considered a critical quality attribute (CQA) because of its potential to affect product safety and efficacy.

Definition And Structure Of Antibodies
Definition And Structure Of Antibodies
Antibodies are shaped like the letter 'Y' and their main job is to bind to an invading antigen, but not to kill the antigen - they do not have this function; the binding is to give the antigen a marker to be destroyed. When phagocytes find the marker to destroy, they come forward and swallow the antibody-bound antigen and digest it.
