Anti-Phosphatidylserine synthase 1 Antibody

PTDSS1, the gene encoding Phosphatidylserine synthase 1, is an integral membrane enzyme of the endoplasmic reticulum that catalyzes the base-exchange reaction producing phosphatidylserine from phosphatidylcholine or phosphatidylethanolamine. This unconjugated rabbit polyclonal reagent from Antibodies.com targets human PTDSS1 and is validated for western blot and immunohistochemistry, supporting research on phospholipid metabolism, membrane biogenesis, and the apoptotic signaling pathway in which phosphatidylserine externalization marks early-stage programmed cell death. The antibody is supplied as 100 µg of purified Ig in a single vial, free of reporter tags so investigators can pair it with their preferred secondary detection reagent. Reactivity is reported for human samples, including cell line lysates and formalin-fixed tissue sections used in immunohistochemistry workflows. For best results, aliquot upon arrival, store refrigerated, and limit freeze-thaw cycles to preserve binding activity over the working shelf life of the reagent.
