Psophocarpus tetragonolobus (PTL/PTA II) (AP)

Alkaline phosphatase (AP) is conjugated to Psophocarpus tetragonolobus Lectin (PTL/PTA II) to show the binding of PTL/PTA II in many applications including Western blotting and ELISA. Alkaline phosphatase is a large protein (140kD) that catalyzes the hydrolysis of phosphate groups from a substrate resulting in a colored or fluorescent product. The optimal enzymatic activity of this protein is between pH 8 and 10, and its reaction rate remains linear, improving sensitivity over time.||Source:|Winged bean||Blood Specificity:|O (-SA)||Sugar Specificity:|N-Acetylgalactosamine, Galactose||Inhibitory Carbohydrate:|N-Acetylgalactosamine||Storage and Stability:|Store product at 4°C.
