Anti-p53 (Ab-5) (Wild type) Mouse mAb (PAb1620)

Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with SP2/0 Ag14 myeloma cells. Recognizes the ~53 kDa wild-type p53 protein.

Recognizes the ~53 kDa wild-type p53 protein in its native conformation in Hs27 cells and breast carcinoma tissue. Does not recognize mutant or denatured p53 protein.

This Anti-p53 (Ab-5) (Wild type) Mouse mAb (PAb1620) is validated for use in Frozen Sections, Immunoblotting, IF, IP, Paraffin Sections for the detection of p53 (Ab-5) (Wild type).

Wild-type p53 has a short half-life and is present in low amounts in cells. Increasing the amount of sample to be immunoprecipitated and applied to the gel may help for visualization. Short incubation times with ³⁵S-Met(≤ 1 hr) will help reduce background. p53 (Ab-5) may also be used to visualize p53 in cytospins or cultured cells using standard horseradish peroxidase or immunofluorescence detection techniques. p53 (Ab-5) preferentially immunoprecipitates wild-type p53; it should not precipitate mutant or denatured p53. Antibody should be titrated for optimal results in individual systems.
