Anti-PITPNB Antibody

PITPNB (phosphatidylinositol transfer protein beta) is a cytosolic lipid transfer protein that shuttles phosphatidylinositol and phosphatidylcholine between membrane compartments, supporting vesicle trafficking, signal transduction, and maintenance of cellular lipid balance. This rabbit polyclonal reagent is raised against the human PITPNB sequence and validated specifically for Western blot detection across human, mouse, and rat samples. The antibody is supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a cryoprotectant, and the 100 µL vial format is intended as a single-use or limited-reuse reagent. Polyclonal reactivity provides broad epitope coverage, which is useful when probing endogenous expression in cell lysates and tissue extracts where multiple regions of the target may be accessible. Researchers commonly apply this reagent from Antibodies.com to studies of membrane trafficking, insulin-stimulated GLUT4 translocation, neural development, and lipid signaling pathways, where PITPNB activity is characterized relative to the closely related PITPNA isoform. Aliquot upon receipt to minimize freeze-thaw cycles and store refrigerated to preserve activity across repeated blots.
