Specificity / Sensitivity
Phospho-Tyrosine Mouse mAb (P-Tyr-100) is a high affinity antibody. ELISAs against a wide variety of phosphopeptides indicate that (a) P-Tyr-100 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-100 interacts with a broad range of tyrosine-phosphorylated proteins. P-Tyr-100 does not cross-react with peptides containing phospho-serine or phospho-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-tyrosine-containing peptides . The antibody was conjugated to Alexa Fluor® 488 under optimal conditions with an F/P ratio of 2-6.
Flow Cytometry
Flow cytometric analysis of K562 cells, untreated (green) or Gleevec®- treated (blue), using Phospho-Tyrosine Mouse mAb (P-Tyr-100) (Alexa Fluor® 488 Conjugate) compared with a nonspecific negative control antibody (red).
Description
Cell Signaling Technology Antibody conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometric analysis of human cells.*The unconjugated antibody, #9411, reacts with phospho-tyrosine in all species tested. CST expects that Phospho-Tyrosine Mouse mAb (P-Tyr-100) (Alexa Fluor® 488 conjugate) will also recognize phospho-tyrosine in all species.
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.
