Quick Overview for p21 antibody (ABIN290473)

Target: p21 (CDKN1A) (Cyclin-Dependent Kinase Inhibitor 1A (p21, Cip1) (CDKN1A))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This p21 antibody is un-conjugated

Application: Western Blotting (WB), Immunohistochemistry (IHC), ELISA, Immunohistochemistry (Paraffin-embedded Sections) (IHC (p)), Immunohistochemistry (Frozen Sections) (IHC (fro))

Clone: WA-1

Product Details anti-p21 Antibody

Specificity: Human and mammalian p21. The antibody is highly specific and shows no cross-reactivity with other closely related mitotic inhibitors. The intracellular protein p21 is a 21 kD protein and also known as wild-type p53-activated fragment 1 (WAF1). It is an inhibitor of cyclin-dependent kinases (Cdks) and proliferating-cell nuclear antigen (PCNA)

Purification: Protein A purified

Immunogen: Recombinant human p21 fusion protein.

Type of Immunogen: Recombinant protein

Application Details

Application Notes: Approved: ELISA, IHC, IHC-Fr, IHC-P, WB

Usage: This antibody is suitable for immunohistochemistry, ELISA and immunoblotting. The antibody detects a 21 kD band corresponding to the p21 protein. MCF7 cells or UV treated fibroblasts are suggested as a positive control for immunoblotting and immunohistochemistry. Methanol/acetone fixed tissue is reactive for immunohistochemistry. The antibody also reacts with breast carcinoma on frozen sections (methanol/acetone fixation) and on paraffin sections (formalin fixation and microwave treatment prior to staining). In ELISA this monoclonal antibody is useful either as a capture antibody (attached to the solid phase) or for detection of p21 protein. This antibody immunoprecipitates monomeric p21 WAF1 and not p21 complexes with other proteins. High level expression of p21 WAF1 requires induction of wild-type p53 expression (e. g. via exposure to DNA damaging agents).
