Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Phe717 of human Sec23A protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
There are two isoforms of Sec23 protein: Sec23A and Sec23B. Both isoforms have been shown in the Sec23/24 complex, which is a component of COPII coat (1). COPII is composed of at least five proteins: the Sec23/24 complex, the Sec13/31 complex, and Sar1. COPII coat is located at the ER/Golgi interface and involved in transport of newly synthesized proteins from the ER to the Golgi apparatus (2). COPII formation is initiated through binding of the activated G protein, Sar1, to the Sec23/24 complex to form a prebudding complex, which directly binds target molecules (2-4). The prebudding complex further recruits Sec13/31 to form mature COPII coat (5,6). In addition to being a COPII component, Sec23 has also been shown to interact with p125 and Sec16 at the transitional ER; these interactions are important for regulation of the COPII transportation function (7,8).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
