Background Information
PKM, also named as OIP3, PK2, PK3, PKM, p58, THBP1, CTHBP and Tumor M2-PK, belongs to the pyruvate kinase family. It is glycolytic enzyme that catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate (PEP) to ADP, generating ATP. It stimulates POU5F1-mediated transcriptional activation. PKM plays a general role in caspase independent cell death of tumor cells. PKM has 2 isoforms named PKM1 and PKM2. The primary pyruvate kinase isoform before tumour development is PK-M1; however, the primary isoform from four independent tumours is PK-M2 (PMID:18337823). This antibody is specific to PKM1 isoform.

FH Pallavi (Verified Customer) (03-31-2025) | I used 1:5000 anti-PKM1 15821-1-AP, it worked perfectly. The reviews were quite helpful to decide which antibody to buy. The delivery was on time. Just make sure the delivery company hands over the package to you. so better to keep a track of the package.
