Research Use Only
For Research Use Only. Not for use in diagnostic procedures.
Species Reactivity
Human, Rat, Mouse, Chicken
This antibody detects phosphotyrosine-containing proteins on SDS-PAGE immunoblots of EGF treated A431 cells, as well as pervanadate treated A431, HeLa, Jurkat, and endothelial cells.
Affinity Purified
Rabbit polyclonal, affinity-purified antibody is supplied in 100 ul phosphate-buffered saline, 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide.
Anti-Phosphotyrosine was generated from a panel of phosphotyrosine-containing peptide immunogens designed from human protein sequences. All peptide sequences used are highly conserved phosphotyrosine motifs.
Preparation and Storage
Store at -20 degree C.
Other Notes
Small volumes of anti-Phosphotyrosine antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
anti-Phosphotyrosine antibody
Phosphorylation of specific tyrosine residues is an important post-translational modification for regulating the activity of most proteins. Stimulation of a variety of cell signaling pathways activates the receptor and non-receptor tyrosine kinases that mediate these protein modifications.Antibodies that can detect phosphotyrosine residues are excellent tools for characterizing changes in the post-translational state of a broad range of phosphotyrosine-containing proteins. Immunoprecipitation of proteins of interest, followed by detection of phosphotyrosine using anti-phosphotyrosine antibody is commonly used to correlate changes in tyrosine phosphorylation state with alterations in protein activity.
Applications Tested/Suitable for anti-Phosphotyrosine antibody
