HMW Host Cell Proteins (HMW HCP) antibody

Details for Product No. ABIN5596741
Escherichia coli (E. coli)
ELISA, Western Blotting (WB)
Purpose Anti-HMW Host Cell Proteins Antibody recognizes high molecular weight protein fractions from E.coli.

Immunogen: Anti-HMW E.Coli Host Cell Proteins Antibody was prepared by repeated immunizations with a mixture high molecular weight (HMW) proteins from E.Coli (BL21).

Immunogen Type: Native Protein

Cross-Reactivity (Details) Reactivity is directed against E.coli Host Cell Proteins. Cross-reactivity with other species is likely but has not been determined. Reactivity against homologues from other sources is not known.

Synonyms: E.Coli Host Cell Protein antibody, HCP antibody, Anti-HCP, Anti-Host Cell Protein, high molecular weight E.Coli HCP proteins antibody, HMW HCP

Background: Anti-HMW Host Cell Proteins Antibody recognizes high molecular weight protein fractions from E.coli. This antibody has been anlyzed by 2D electrophoresis western blot to assure highest possible coverage of E.coli HCP. Host Cell Proteins are process-related impurities derived from a host cell expression system that may be present in trace amounts in a final drug substance. HCP Antibodies are used to detect impurities in biologically-based therapeutics. Detecting impurities often unseen by 1-D electrophoresis, a 2D electrophoresis western blot analysis delivers more complete insight into the immunocoverage of protein components of the host cell lysate.

Purification This whole rabbit antiserum was prepared by delipidation and defibrination followed by the addition of buffer salts and preservative.
Sterility Sterile filtered
Alternative Name HMW E.Coli Host Cell Proteins
