EK-800-130-ECP 大肠杆菌蛋白（5株）宿主细胞蛋白（HCP）ELISA检测试剂盒E Coli proteins (5 strains) host cell proteins (HCPs) ELISA kit, 96 tests

产品介绍：
The E. coli HCP ELISA kit is based on the binding of E. coli HCP proteins in samples to two antibodies, one immobilized on the microwells, and the other conjugated to horseradish peroxidase (HRP) in solution. After a washing step, chromogenic substrate (TMB) is added and color is developed by the enzymatic reaction of HRP on the substrate, which is directly proportional to the amount of antigen present in the sample. Stopping Solution is added to terminate the reaction, and absorbance at 450nm is then measured using an ELISA microwell reader. The level of E. coli proteins in samples is determined relative to E. coli HCP Standards.
