Phosphotyrosine Antibody [clone PY20] (V2359)

Description

Protein phosphorylation is a fundamental event in the regulation of a large number of intracellular processes. Phosphorylation of specific tyrosine residues is the result of activation or stimulation of their respective protein tyrosine kinases. The phosphorylated proteins can be auto-phosphorylated kinases or certain cellular protein substrates. Tyrosine-phosphorylated proteins are involved in signal transduction and in the regulation of cell proliferation. Antibody to phosphotyrosine provides an excellent tool for the detection, characterization, and purification of phosphotyrosine containing proteins. This antibody shows no cross-reaction with other phosphoamino acids and is superb for multiple applications including staining of formalin/paraffin tissues.

Application Notes

The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the Phosphotyrosine antibody to be titered up or down for optimal performance.

1. No pretreatment is required for staining of formalin-fixed, paraffin-embedded tissues.

Immunogen

Phosphotyrosine conjugated to KLH was used as the immunogen for this antibody.

Storage

Store the Phosphotyrosine antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
