Phospho-Tyrosine Agarose-conjugated Antibody

  • Specificity
    Detects endogenous proteins containing phosphorylated Tyrosine residues. ELISA and 2D Western blot analyses using ligand- and pervanadate-treated cell lysates indicate that clone 179003 binds Phospho-Tyrosine in a broad manner largely independent of the surrounding amino acid sequence. Does not cross-react with proteins or peptides containing phosphorylated serine or threonine residues.
  • Source
    Monoclonal Mouse IgG1 Clone # 179003
  • Formulation
    Phosphate-buffered saline (PBS) with preservative.
  • Label
  • Immunoprecipitation
    10 µL/500 µg cell lysate
    See below
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
Immunoprecipitation of Human Phospho-tyrosine. A431 human epithelial carcinoma cell line was untreated (-) or treated (+) with 200 mM pervanadate (PV) for ???time. Phospho-tyrosine was immunoprecipitated from 500 μg of cell lysate following incubation with 10 µg Mouse Anti-Phospho-Tyrosine Agarose-conjugated Monoclonal Antibody (Catalog # AGM1676) for 16 hours at 2 - 8 ºC. Immunoprecipitated phospho-tyrosine was detected by Western blot using ??? µg Phospho-Tyrosine Biotinylated Monoclonal Antibody (left panel, Catalog # BAM1676) or Human EGF R/ErbB1 Biotinylated Antigen Affinity-purified Polyclonal Antibody (right panel, Catalog # BAF231).

Preparation and Storage
  • Reconstitution
    Sterile PBS to a final concentration of 0.5 mg/mL.
  • Stability & Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: Phospho-Tyrosine
Phosphorylation of tyrosine residues in signaling proteins by protein tyrosine kinases mediates a variety of cellular processes, including cell growth, differentiation, adhesion, motility, death, and metabolism. Dysregulation of tyrosine phosphorylation has been implicated in the development of many human diseases, such as diabetes and cancer. Antibodies specific for phospho-tyrosine have been invaluable reagents in the studies of signaling pathways initiated by tyrosine phosphorylation.
  • Alternate Names:
    2 amino 3(4 hydroxyphenyl) propanoic acid; 4 hydroxyphenylalanine; PhosphoTyrosine; pTyrosine; Tyrosine
