Anti-PPAT Antibody

Raised in rabbit against human PPAT (phosphoribosyl pyrophosphate amidotransferase), this unconjugated polyclonal antibody from Antibodies.com is supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, in a 100 µl vial. The reagent recognizes the amidophosphoribosyltransferase that catalyzes the first committed step of de novo purine biosynthesis and is validated for western blot and immunohistochemistry on human and rat specimens, supporting work in cancer cell lines, tumour xenografts, and matched normal tissues where PPAT expression is being mapped or compared across conditions. Storage at -20 °C in single-use aliquots helps preserve activity across multiple freeze-thaw cycles, and the 50% glycerol cryoprotectant maintains antibody stability for ongoing laboratory use.
