        Host Cell Protein (HCP) Antibody Generation

Host Cell Protein Antibody Generation Overview


Biopharmaceuticals require products to be free of host cell protein (HCP) contaminants.  These HCPs may be left behind during the purification process from the expression hosts, such as E. coli, insect, or mammalian cells.   To investigate the presence of residual contamination during the bioprocessing and the final biopharmaceutical product, development of custom polyclonal antibody reagents with maximum coverage against native HCP extracts is required. Please see US FDA Guidelines for Bioanalytical Validation.

Rockland provides multiple customizable options for HCP antibody development.  These options allow flexibility to the researcher to develop early stage through late stage HCP detection reagents.

TrueBlot® Mouse Western Blot Kit


The Mouse TrueBlot® Western Blot Kit contains the critical supporting reagents, buffers, and substrates for GFP immunoprecipitation and Western blotting of samples using TrueBlot second step immunoblotting reagents in conjunction with your own primary IP antibody and primary (Mouse IgG) Western blotting antibody. TrueBlot technology enables unhindered detection of protein bands of interest which would otherwise be obscured by the presence of reduced and denatured heavy and light chain immunoglobulin in the blot (as detected by the conventional immunoblotting HRP anti-mouse IgG reagent).
