This is a synthetic peptide designed for use in combination with anti-SAR1B antibody (Catalog #: ARP56243_P050). It may block above mentioned antibody from binding to its target protein in western blot and/or immunohistochecmistry under proper experimental settings. There is no guarantee for its use in other applications.
SAR1B is involved in transport from the endoplasmic reticulum to the Golgi apparatus. SAR1B is activated by the guanine nucleotide exchange factor PREB. SAR1B is involved in the selection of the protein cargo and the assembly of the COPII coat complex.
