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 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)

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). 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.
