Technical Data
p21 (Activating Fragment 1, CAP20, CDK-interacting Protein 1, CIP1, Cyclin-dependent Kinase Inhibitor 1A, CDKN1A, CDKN1, DNA Synthesis Inhibitor, Melanoma Differentiation-associated Protein 6, MDA6, MDA6, p21CIP1, p21-CIP1, PIC1, SDI1, Wildtype p53 Activa
Protein p21, also known as wild-type p53-activated fragment 1 (WAF-1), inhibits cyclin dependent kinases and is regulated by p53; overexpression of this protein inhibits the proliferation of mammalian cells.

Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunohistochemistry: Paraffin
