p21 Antibody [WAF21-1]

Primary Antibodies

Aliquot and Store at 2-8˚ C. Avoid freez-thaw cycles.

p21WAF1 is a specific inhibitor of cdk s and a tumor suppressor involved in the pathogenesis of a variety of malignancies. The expression of this gene acts as an inhibitor of the cell cycle during G1 phase and is tightly controlled by the tumor suppressor protein p53. Its expression is induced by the wild type, but not mutant, p53 suppressor protein. Normal cells generally display a rather intense nuclear p21 expression. Loss of p21 expression has been reported in many carcinomas (gastric carcinoma, non-small cell lung carcinoma, thyroid carcinoma).

None

0.2 mg/mL

Immunofluorescence: 1-2 ug/ml
Western Blot: 1-2 ug/ml
Immunohistochemistry (FFPE): 2-4 ug/ml for 30 min at RT (1)
Prediluted format : incubate for 30 min at RT (2)
Optimal dilution of the p21 antibody to be determined by the researcher.

1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
