Anti-COPB2 Antibody

Generated in a rabbit host, this polyclonal reagent from Antibodies.com targets COPB2, the beta subunit of the COPI coatomer complex that mediates retrograde vesicle trafficking between the Golgi apparatus and the endoplasmic reticulum. The antibody is supplied as 100 µl of a 1 mg/ml stock in PBS with 0.1% sodium azide as preservative and 50% glycerol as cryoprotectant, and the unconjugated format leaves the choice of secondary reporter open to the end user. Validated applications include western blot, immunohistochemistry, and immunofluorescence, with reactivity confirmed against human, mouse, and rat samples so that cell line panels and primary tissue can be compared within a single workflow. COPB2 has been studied in the context of Golgi integrity, intracellular transport, and several oncology models, and this reagent supports those investigations by offering a polyclonal reagent capable of recognising multiple epitopes on the target protein. The vial format and the included glycerol also allow the stock to be kept frozen in working aliquots to limit repeated freeze-thaw cycles of the parent tube.
