Product Overview
Clone 27O45 is a rabbit monoclonal antibody that recognizes oxysterol-binding protein-related protein 1 (gene OSBPL1A) in human, mouse and rat samples and is validated for Western blot, ICC/IF and flow cytometry. The predicted molecular weight is 108.5 kDa; the supplier reports observed bands at 50, 108 kDa.
ORP1 (OSBPL1A) is an oxysterol-binding protein-related protein that binds sterols and phospholipids. Its long form associates with RAB7 on late endosomes and lysosomes, where it influences endosome positioning and cholesterol transfer to the ER.
