Aldolase (fructose-bisphosphate aldolase EC 4.1.2.13) catalyzes the reversible conversion of fructose-1 6-bisphosphate to glyceraldehyde 3-phosphate and dihydroxyacetone phosphate. Three isoforms of aldolase (A B and C) are differentially expressed during development. Aldolases have been recognized as positive regulators of the Wnt signaling pathway. Deficiency of aldolases is associated with myopathy and hemolytic anemia.The Aldolase Activity Colorimetric Assay Kit is a simple and high throughput assay for measuring aldolase activity in serum plasma and a variety of tissues and cells. Aldolase activity is determined by measuring a colorimetric product with absorbance at 450 nm (A450) proportional to the enzymatic activity present. One unit of aldolase is the amount of enzyme that generates 1.0 mumole of NADH per minute at pH 7.2 at 37 C.
