Other Names IRS-1, IRS1, Insulin receptor substrate-1
All Sites Human: Ser323; Mouse: Ser318; Rat: Ser318
Storage/Stability Store at -20℃/1 year
Form Or Antibody
Form of Antibody Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
Immunogen The antiserum was produced against synthesized phosphopeptide derived from human IRS-1 around the phosphorylation site of serine 323 (P-G-SP-F-R).
Purification The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Specificty Sensitivity
Specificity/Sensitivity IRS-1 (Phospho-Ser323) antibody detects endogenous levels of IRS-1 only when phosphorylated at serine 323.
