Pembrolizumab is offered in laboratory-suitable formats for research and production. It belongs to the IgG4 monoclonal antibody class with a molecular formula of C85H170N4OS and a molecular weight of 1296.4. This compound is a humanized antibody that selectively binds to programmed death-1 (PD-1) proteins, inhibiting their interaction with programmed death ligand-1 and -2 (PD-L1/2), thereby enhancing antitumor immune responses. Pembrolizumab requires careful handling due to its biological origin. It should be stored at temperatures between 2°C and 8°C and protected from light. Potential applications of pembrolizumab include treatment of various types of cancer, such as melanoma, non-small cell lung cancer, and Hodgkin lymphoma.
