E. coli HCP ELISA Kit (host cell protein)

Product details

E. coli HCP ELISA Kit (host cell protein) ab240997 is a sandwich ELISA used to measure impurites caused by E. coli host cell proteins (HCP) with a sensitivity of 30 ng/mL.

How the assay works

The provided 96-well plate has been pre-coated with Rabbit anti-E. coli HCP antibodies to capture E. coli proteins from biological samples. Following an incubation to allow capture of the E. coli protein by the antibodies on the plate, a second anti- E. coli HCP antibody, conjugated with biotin, is added and incubated to allow it to bind to the captured E. coli proteins. After incubation, the plate is washed and a Streptavidin-HRP conjugate is added and incubated for 30 min. The Streptavidin-HRP conjugate will be captured by any biotin labeled antibody bound to the plate. Following a wash step to remove unbound conjugate, TMB substrate is added and is converted by the captured HRP to a colored product in proportion to the amount of HCP bound to the plate. After a short incubation to allow color development, the reaction is stopped and the intensity of the generated color is detected in a spectrophotometer plate reader capable of measuring 450nm wavelength.
