Anti-COPB1 Antibody

COPB1 (Coatomer Protein Complex Subunit Beta 1) is a ~107 kDa subunit of the heptameric COPI coatomer complex that drives retrograde vesicle budding from the Golgi apparatus back to the endoplasmic reticulum, supporting cargo retrieval and Golgi compartment maintenance in eukaryotic cells. This unconjugated rabbit polyclonal antibody from Antibodies.com is raised against the human COPB1 target and supplied at a 100 µl volume, ready for dilution into standard immunodetection workflows. Verified applications include western blot analysis of the COPB1 band in cell lysates and immunohistochemistry on formalin-fixed, paraffin-embedded tissue sections, enabling studies of COPI coatomer assembly, intra-Golgi trafficking, and secretory pathway function in human-derived samples.
