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 BTK around the phosphorylation site of tyrosine 551 (D-E-YP-T-S).
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.
BTK (phospho-Tyr551) antibody detects endogenous levels of BTK only when phosphorylated at tyrosine 551.
