The chemiluminescent Western Blot Kit for the Detection of E. coli Host Cell Proteins (HCP) combines all necessary reagents with a rapidly proven protocol for the detection of E. coli HCP contamination in products produced by recombinant expression in E. coli host cells.
Use the kit for the detection of host cell protein contaminations by 1D-Western blot, 2D-Western blot or by dot blot. It can be used as a process development tool or routine quality control method to monitor the optimal removal of HCP contaminants.
After protein separation and transfer, the membrane is probed with Anti-Host Cell Proteins Antibody. The membrane bound antibody-antigen complex is detected by the addition of a secondary antibody bound to the enzyme horseradish peroxidase. The enzyme reacts with Femtomax, a special formulation of luminol, an extremely sensitive, non-radioactive substrate that emits light (chemiluminescence) and allows visualization with X-ray film or other imaging techniques, including highly sensitive CCD cameras and imaging systems.
The femtomaxes reagent (FEMTOMAX-020 or FEMTOMAX-110) is not included in this kit and must be purchased separately.
E. Coli HCP Antibody used in Chemiluminescent Western Blot Kit
The antibody contained in this kit recognizes high and low molecular weight protein fractions of E. coli. This antibody has been validated by 2D Western Blot electrophoresis to ensure the highest possible coverage of E. coli HCP. Western blot 2D electrophoresis analysis provides a more comprehensive insight into the immune coverage of host cell lysate protein components. It detects impurities that are often not visible through 1-D electrophoresis. The Anti-Host Cell Proteins antibody contained in this kit detects over 300 E.coli proteins and is suitable for Western blotting.
