p21/CIP1/CDKN1A Antibody (CIP1/823) Summary

Recombinant full-length human CDKN1A protein
This MAb recognizes a 21kDa protein, identified as the p21WAF1 tumor suppressor protein. This MAb is highly specific to p21 and shows no cross-reaction with other closely related mitotic inhibitors. 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).

  • Western Blot 1 - 2 ug/ml
  • Flow Cytometry 0.5 - 1 ug/million cells in 0.1 ml
  • Immunocytochemistry/Immunofluorescence
  • Immunohistochemistry
  • Immunohistochemistry-Paraffin 2 - 4 ug/ml
Application Notes
Hu-chromosome location: 6p21.31
Immunohistochemistry-Paraffin 2 - 4 ug/ml for 30 minutes at RT; 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 minutes. The 7mL size is a pre-diluted size and no additional dilutions are required before using this item for the intended application.
Theoretical MW
21 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
