Phosphotyrosine (FITC)
Description:
Protein tyrosine phosphorylation has been the subject of intense investigation for over two decades. Tyrosine phosphorylation is catalyzed by members of the tyrosine kinase superfamily. To date, approximately 90 members of this superfamily have been identified in the human genome. Levels of phosphorylation of tyrosine residues within cellular proteins are observed to increase in response to growth factors, cytokines, insulin, extracellular matrix components, and other stimuli. Tyrosine phosphorylation has several effects, including the regulation of enzyme activity, as well as the localization of enzyme activity through the generation of docking sites for proteins bearing SH2 domains.

Applications:
Suitable for use in Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Immunocytochemistry: 1.5-15ug/ml of this lot detected phosphotyrosine-containing proteins in EGFstimulated human A431 cells.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20°C or colder. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
