Description

Background:
Pembrolizumab, sold under the brand name Keytruda, is a humanized antibody used in cancer immunotherapy that treats melanoma, lung cancer, head and neck cancer, Hodgkin lymphoma, stomach cancer, and cervical cancer. It is an immune checkpoint inhibitor against PD-L1, inhibiting lymphocytes’ PD-1 receptors, blocking the ligands that would deactivate it and prevent an immune response. It is on the World Health Organization’s List of Essential Medicines.

Intended Use:
For Estimation of Pembrolizumab (KEYTRUDA) in human serum and plasma. Please note the kit has not been optimized to be used for any other animal species. Should you require a specific sera tested, please connect with us at sales@krishgen.com for optimization.

Principle:
The method employs the quantitative sandwich enzyme immunoassay technique. Antibodies to Pembrolizumab are pre-coated onto microwells. Samples and standards are pipetted into microwells and human Pembrolizumab present in the sample are bound by the capture antibody. Then, a HRP (horseradish peroxidase) conjugated anti-pembrolizumab antibody is pipetted and incubated. After washing microwells in order to remove any non-specific binding, the ready to use substrate solution (TMB) is added to microwells and color develops proportionally to the amount of Pembrolizumab in the sample. Color development is then stopped by addition of stop solution. Absorbance is measured at 450 nm.
