Target

  • Relevance
    The phosphorylation of specific tyrosine residues has been shown to be a primary mechanism of signal transduction during normal mitogenesis, cell cycle progression and oncogenic transformation, its role in other areas such as differentiation and gap junction communication, is a matter of active and ongoing research. Antibodies that specifically recognize phosphorylated tyrosine residues have proved to be invaluable to the study of tyrosine phosphorylated proteins and the biochemical pathways in which they function.

Images

  • Serially diluted ab179530 was bound to immobilised phospho- or control peptides (STAT1 (phospho S727), STAT1 control, STAT5 (phospho T694), STAT5 control); 1 microgram per mL).

    The antibody was detected by Goat anti-Rabbit HRPO and signal was developed by TMB substrate.

  • Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized C2C12 (Mouse myoblast cell line) cells labeling Phosphotyrosine with ab179530 at 1/100 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/400 dilution (green). Cytoplasm staining on C2C12 cells is observed. The expression increased after treatment with H2O2 (2mM) for 10 minutes. The nuclear counterstain is DAPI (blue). Tubulin is detected with ab7291 (anti-Tubulin mouse mAb) at 1/500 dilution and ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution (red).
    The negative controls are as follows:-
    -ve control 1: - ab179530 at 1/100 dilution followed by ab150120 (AlexaFluor®594 Goat anti-Mouse secondary) at 1/500 dilution.
    -ve control 2: - ab7291 (anti-Tubulin mouse mAb) at 1/500 dilution followed by ab150077 (Alexa Fluor®488 Goat Anti-Rabbit IgG H&L) at 1/400 dilution.

     

  • Dot blot analysis of INSR/IGF-1R (pY1009) phospho peptide (lane 1) and INSR/IGF-1R non-phospho peptide (lane 2) labelling Phosphotyrosine with ab179530 at a dilution of 1/1000. A peroxidase-conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody (1/2500).

    Blocking and dilution buffer: 5% NFDM/TBST.

    Exposure time: 3 minutes.

  • Phosphotyrosine was immunoprecipitated from 1mg of A431 (Human epidermoid carcinoma) whole cell extract treated with 1mM pervanadate for 30 minutes with ab179530 at 1/100 dilution. Western blot was performed from the immunoprecipitate using ab179530 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500 dilution. Lane 1: A431 treated with 1mM pervanadate for 30 minutes whole cell extract. Lane 2: PBS instead of A431 whole cell extract.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
