Background: 6-phosphofructo-2-kinase/fructose-2, 6-biphosphatase 4 also known as PFKFB4 is an enzyme which in humans is encoded by the PFKFB4 gene. The protein encoded by this gene is one of four bifunctional kinase/phosphatases that regulate the concentration of the glycolytic byproduct fructose-2, 6-bisphosphate (F2, 6BP). The encoded protein is highly expressed in cancer cells and is induced by hypoxia. This protein is essential to the survival of cancer cells under conditions of hypoxia, because it increases the amount of F2, 6BP and ATP at a time when the cell cannot produce much of them. This finding suggests that this protein may be a good target for disruption in cancer cells, hopefully imperiling their survival. Several transcript variants encoding different isoforms have been found for this gene.

Immunogen: E.coli-derived human PFKFB4 recombinant protein (Position: M1-K298). Human PFKFB4 shares 97.3% and 97% amino acid (aa) sequence identity with mouse and rat PFKFB4, respectively.

Clonality: Polyclonal

Contents: Each vial contains 4 mg Trehalose, 0.9 mg NaCl, 0.2 mg Na2HPO4.

Purification: Immunogen affinity purified.

Reconstitution: Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.
