The addition of 0.05% Tween 20 in the blocking buffer and primary antibody incubation buffer is recommended to aid in detection by Western blot. Individual optimization may be required.


This antibody was raised against a peptide within the C-terminal region of human PKM2.


Purified IgG in PBS with 30% glycerol, 0.035% sodium azide and 0.2 mg/ml BSA.


PKM2 antibody (pAb) tested by Western blot.

PKM2 pAb tested by Western blot.
PKM2 detection by Western blot. The analysis was performed using 30 µg HeLa whole cell extract and PKM2 at a 1:1,000 dilution.


PKM2 (pyruvate kinase M2 isoform) is a glycolytic enzyme that catalyses the conversion of phosphoenolpyruvate to pyruvate. In mammals, the M1 isoform (PKM1) is expressed in most adult tissues. The M2 isoform (PKM2), an alternatively-spliced variant of M1, is expressed during embryonic development, is upregulated in human cancer cells and has been implicated in transcriptional regulation. Recently PKM2 has been described to bind to Histone H3 and phosphorylate threonine 11 (H3T11ph) which implicates PKM2 as an epigenetic regulator of gene expression.

Positive Control

Active Motif's HeLa whole-cell extract (Catalog No. 40050) can be used as a positive control for PKM2 antibody.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
