Product Overview
This rabbit polyclonal antibody targets 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 2 (gene PFKFB2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 58.5 kDa, and the supplier reports an observed band at about 58 kDa.
PFKFB2 is the heart isoform of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase. By controlling the level of fructose 2,6-bisphosphate, a strong activator of phosphofructokinase-1, it links hormonal signals such as insulin and adrenaline to the rate of glycolysis in cardiac muscle and other tissues.
