Anti-ESR1 (phospho S167) Antibody - Identical to Abcam (ab131105)

Rabbit polyclonal IgG antibody targeting Estrogen Receptor alpha (ESR1) phosphorylated at Ser167, offered by Antibodies.com as a primary antibody reagent. The unconjugated product is raised in rabbit and affinity purified, and is validated for Western Blot (WB), Immunohistochemistry (IHC) and Immunocytochemistry/Immunofluorescence (ICC/IF) applications.

The antibody was generated against a synthetic phosphorylated peptide centred on the S167 residue of human Estrogen Receptor alpha (ESR1; NP_000116.2). Reactivity with Human samples is reported on the manufacturer's datasheet, while Antibodies.com additionally lists Mouse. The corresponding protein has a molecular weight of 66 kDa. Recommended starting dilutions are WB 1:500–1:2,000, IHC 1:50–1:100, and ICC/IF 1:100–1:200; concentration is lot specific.

The reagent is supplied as a liquid in Phosphate Buffered Saline (pH 7.3) containing 50% glycerol and 0.01% thiomersal. It is shipped at 4°C and should be aliquoted and stored at −20°C on receipt, with freeze/thaw cycles avoided.
