Anti-P-Tyr | Phosphotyrosine (clone G104)

Tyrosine phosphorylation is considered to be one of the key steps in signal transduction and regulation of enzymatic activity. Phosphotyrosine antibodies are helpful in facilitating the identification of tyrosine kinase substrates.

Antibody reacts with phosphotyrosine and detects the presence of phosphotyrosine in proteins of both unstimulated and stimulated cell lysated, Does not cross react with phosphoserine or phosphothreonine

Phosphotyrosine, alanine and glyceine in a 1:1:1 ratio polymerized in the presence of keyhole limpet hemocyanin KLH with 1-ethyl-3- (3’-dimentrylaminopropyl) carbodiimide

1 µg/mL of this antibody is sufficient for detection of phosphorylated tyrosine residues in 10 µg of rat tissue lysate by colorimetric immunoblot analysis

Store at -20°C for one year; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
