Anti-SAR1B Antibody

This rabbit polyclonal reagent from Antibodies.com is raised against an internal peptide of human SAR1B and is affinity-purified from rabbit antiserum using epitope-specific immunogen chromatography. It is supplied at 1.0 mg/mL in 50 µl of phosphate-buffered saline (without Mg²⁺ and Ca²⁺), pH 7.4, containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol, with the IgG fraction remaining unconjugated for downstream flexibility. Validated applications cover Western blotting and immunohistochemistry, where the reagent detects endogenous levels of total SAR1B protein across human, mouse, and rat samples, making it well suited for COPII vesicle trafficking and ER-to-Golgi transport studies. The antibody is shipped at 4°C and, upon receipt, should be aliquoted and stored at –20°C with freeze/thaw cycles avoided to preserve binding activity. As an unconjugated polyclonal, it is straightforward to pair with secondary reporters of the researcher's choice, and the rabbit IgG formulation is suitable for a broad range of chromogenic and fluorescence detection workflows in cell and tissue preparations.
