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 CD19 around the phosphorylation site of tyrosine 531 (D-S-YP-E-N).
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.
Reactivity:
Human, Mouse
SwissProtNo:
P15391
Applications:
WB: 1:500~1:1000 ELISA: 1:5000
Other Names:
B-lymphocyte surface antigen B4, CD19, Leu-12
Specificity Sensitivity:
CD19 (Phospho-Tyr531) antibody detects endogenous levels of CD19 only when phosphorylated at tyrosine 531.
