Protocols
Specificity / Sensitivity
Phospho-Tyrosine Mouse mAb (P-Tyr-100) (Biotinylated) is prepared by biotinylation of the antibody via primary amines. Biotinylated antibody is useful for detection or purification of tyrosine-phosphorylated proteins using avidin-biotin binding. This antibody does not cross-react with proteins phosphorylated at serine or threonine. (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 phospho-Tyr-containing peptides . Antibody is purified by protein A chromatography.
Western Blotting
Western blot analysis of extracts from NIH/3T3 cells untreated and treated with sodium vanadate (1 mM for 30 minutes), using 75 ng/ml Phospho-Tyrosine Mouse mAb (P-Tyr-100) (Biotinylated) (A), then detected by Anti-biotin Antibody, HRP-linked #7075. Western blot analysis of the same extract using 750 ng/ml Phospho-Tyrosine Mouse mAb (P-Tyr-100) #9411, then detected by Anti-mouse IgG, HRP-linked Antibody #7076 (B).
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human breast carcinoma, untreated (left) or λ-phosphatase-treated (right), using Phospho-Tyrosine mAb (P-Tyr-100) (Biotinylated).
Background
Tyrosine phosphorylation plays a key role in cellular signaling (1). 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 provide exceptionally sensitive new tools of increased utility for studying tyrosine phosphorylation and monitoring tyrosine kinase activity in high throughput drug discovery.
