Used in biomedical research to quantify levels of the M2-type pyruvate kinase (PKM2) protein in cell lysates, tissue extracts, and biological fluids. This ELISA kit is particularly valuable in cancer research, as PKM2 is overexpressed in many tumor types and plays a key role in regulating cancer cell metabolism. It enables researchers to monitor PKM2 expression during disease progression, assess response to therapeutic agents, and investigate its role in metabolic reprogramming. The assay provides a sensitive and specific method for high-throughput analysis in studies related to oncology, immunology, and cellular metabolism.
