Immunoprecipitation
Not Western Blot
Paraffin Sections
Application NotesFrozen Sections (see applications references)
Immunoblotting (not recommended)
Immunofluorescence (1-20 μg/ml)
Immunoprecipitation (1 μg per sample)
Paraffin Sections (5 μg/ml, heat pre-treatment required)
Application CommentsWild-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.
