Phospho-Tyrosine Mouse mAb (P-Tyr-100) (Biotinylated) #9417

Applications Reactivity Source Isotype
W IP IHC-P All Mouse IgG1

Applications Key:  W=Western Blotting  IP=Immunoprecipitation  IHC-P=Immunohistochemistry (Paraffin)
Reactivity Key: All=All species expected

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 derived from mice immunized with phospho-Tyr-containing peptides (KLH coupled). 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 lambda 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 Mouse mAbs developed by CST (P-Tyr-100, #9411 and P-Tyr-102, #9416) provide exceptionally sensitive new tools of increased utility for studying tyrosine phosphoyrlation and monitoring tyrosine kinase activity in high throughput drug discovery.
