The datasheet shows a Western blot using ab2722 after the protein is immunoprecipitated. Can this antibody be used on a lysate, instead of immunoprecipitated protein? |
|||||||||
ANSWER: |
Yes, this antibody can be used on a tissue lysate. I would recommend the following conditions: 1) Load 10-30 ug of the cell lysate, 2) Block the membrane with 5%BSA, 0.1% Tween in overnight at 4C, 3) Incubate the blocked blot with primary antibody at a concentration of 0.1-1.0 ug/mL in Tris buffered saline supplemented with 3% BSA and 0.1% Tween 20 for 2 hours at room temperature, 4) Wash the blot with several changes of Tris buffered saline supplemented with 0.1% Tween 20, 5) Detect the antibody band using an appropriate secondary antibody, in conjunction with your chemiluminescence reagents and instrumentation. I hope this information helps you, please do not hesitate to contact me if you have further questions, |

Peptide Competition: VAV 1 protein immunoprecipitated from K562 cell extracts was resolved by SDS-PAGE on a 10% Tris-glycine gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4oC, then were incubated with 0.50 µg/mL ab4763 antibody for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with: no peptide (1), the non-phosphopeptide corresponding to the immunogen (2), a generic phosphotyrosine containing peptide (3), or, the phosphopeptide immunogen (4). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and signals were detected using the Tropix WesternStar method. The data show that only the peptide corresponding to ab4763 blocks the antibody signal, thereby demonstrating the specificity of the antibody.
