Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
Storage/Stability:
Store at -20℃/1 year
class="eg_cn_title"Immunogen:
The antiserum was produced against synthesized phosphopeptide derived from human HSP27 around the phosphorylation site of serine 78 (A-L-SP-R-Q).
Purification:
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatogramphy using non-phosphopeptide corresponding to the phosphorylation site.
HSP27 (Phospho-Ser78) antibody detects endogenous levels of HSP27 only when phosphorylated at serine 78.
