Phospho-Tyrosine Mouse mAb (P-Tyr-102) #9416
|W IP IHC-P F E-P||All||Endogenous||Mouse IgG1|
Reactivity Key: All=All species expected
Species cross-reactivity is determined by western blot.
Specificity / Sensitivity
Phospho-Tyrosine Mouse mAb (P-Tyr-102) is a high affinity IgG1 monoclonal antibody. ELISAs using a wide variety of phospho-peptides show that P-Tyr-102 binds phospho-Tyr in a manner largely independent of the surrounding amino acid sequence.2D gel western blot analysis of pervanadate-treated cell extracts also shows that P-Tyr-102 interacts with a broad range of tyrosine-phosphorylated proteins. P-Tyr-102's fine specificity in terms of the sequence context in which it can recognize phospho-tyrosine seems to differ slightly from that of P-Tyr-100 #9411. P-Tyr-102 does not recognize peptides containing phospho-Ser or phospho-Thr. (U.S. Patent No's.: 6,441,140; 6,982,318; 7,259,022; 7,344,714; U.S.S.N. 11,484,485; and all foreign equivalents.)
Source / Purification
Monoclonal antibody is produced by immunizing animals with synthetic phospho-Tyr-containing peptides.
Western blot analysis of extracts from sodium vanadate treated (3 mM for 0.5 hour) NIH/3T3 cells, using Phospho-Tyrosine Mouse mAb (P-Tyr-102).
Western blot analysis of extracts from Jurkat cells treated with 1 mM pervanadate for 30 minutes prior to lysis. Proteins were separated by 2D electrophoresis prior to blotting.

Immunohistochemical analysis of paraffin-embedded NCI-H1650 xenograft untreated (left) or lambda-phosphatase-treated (right), using Phospho-Tyrosine Mouse mAb (P-Tyr-102).
Flow cytometric analysis of NIH/3T3 cells, untreated (blue) or pervanadate-treated (green), using Phospho-Tyrosine Mouse mAb (P-Tyr-102) compared with a nonspecific negative control antibody (red).
Phospho-Tyrosine Mouse mAb (P-Tyr-102) ELISA Assay: Signal-to-noise ratio of phospho- versus nonphospho-peptides. (Y* denotes phosphorylated tyrosine.)
Tyrosine phosphorylation plays a key role in cellular signaling (1). Research studies have shown that in cancer, unregulated tyrosine kinase activity can drive malignancy and tumor formation by generating inappropriate proliferation and survival signals (2). Antibodies specific for phospho-tyrosine (3,4) have been invaluable reagents in these studies. The phospho-tyrosine monoclonal antibodies developed by Cell Signaling Technology are exceptionally sensitive tools for studying tyrosine phosphorylation and monitoring tyrosine kinase activity in high throughput drug discovery.
