Total cell lysate (15 µg protein) from non-treated and 1mM Pervanadate treated HeLa cells (30 min treatment) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to nitrocellulose, and probed with 1:2000 (0.25 µg/mL) diluted purified anti-Phosphotyrosine antibody (clone PY20) (upper). Proteins were visualized using 1:3000 diluted HRP goat anti-mouse-IgG secondary antibody (clone Poly4053, Cat. No. 405306) and chemiluminescence detection. Direct-Blot™ HRP anti-β-actin Antibody (1:2000 diluted, clone 2F1-1, Cat. No. 643807) was used as a loading control (lower). Lane M is the MW ladder.

    NIH3T3 cells were non-treated (A and B) or treated with 1mM pervanadate for 30 minutes (C and D) and then were fixed with 4% paraformaldehyde (PFA) for 10 minutes, permeabilized with 0.5% Triton X-100 for 3 minutes, and blocked with 5% FBS for 60 minutes. Then the cells were intracellularly stained overnight at 4°C with 1: 2500 diluted (0.2 µg/ml, A and C) and 1: 1000 diluted (0.5 µg/ml, B and D) purified anti-Phosphotyrosine antibody, clone PY20 followed by 1:200 diluted (2.5µg/mL) Alexa Fluor® 594 (red) conjugated goat anti-mouse IgG (Cat no. 405326) incubation for one hour at room temperature. Nuclei were counterstained with DAPI (blue). The image was captured with a 60X.

Description

Phosphorylation is a common modification of proteins that can result in alterations in protein function, protein-protein association, cellular localization, and protein-half life. Phosphorylation can occur on threonine, serine, and tyrosine residues. The PY20 monoclonal antibody recognizes phosphorylated tyrosine residues in all species tested (human, mouse, rat, dog, chicken, and frog). The PY20 antibody has been shown to be useful for flow cytometry, immunoprecipitation, Western blotting, and immunofluorescence staining.

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. Suggested working dilution(s): Use 0.125 - 1.0 µg per ml antibody dilution buffer per mini-gel. Do not use dilution or blocking buffers containing milk as they may interfere with antibody binding to proteins of interest. Dilution and blocking buffers containing 4% bovine serum albumin are recommended for use with this antibody. For immunocytochemistry, a concentration range of 0.2 - 0.5 μg/ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats) include: immunoprecipitation1,2, Western blotting1,2, immunocytochemistry3.
