Product Specific Information
Immunohistochemistry (PFA fixed): Incubate antibody for 30 min at room temperature.
Staining of formalin-fixed tissues requires heating tissue sections in 10 mM Tris with 1 mM EDTA, pH 9.0, for 45 min at 95°C, followed by cooling at room temperature for 20 minutes.
Target Information
Protein p21 is a tumor suppressor protein that inhibits Cyclin-dependent kinases (CDK) and is transcriptionally activated by p53.
It plays a key role in cellular response to genotoxic stress and is a major transcriptional target of p53.
In the nucleus, p21 binds and inhibits Cdk1 and Cdk2, blocking transitions from G1 to S phase or G2 to mitosis after DNA damage, allowing DNA repair.
In the cytoplasm, p21 has anti-apoptotic effects by inhibiting caspase 3 and apoptotic kinases ASK1 and JNK.
P21 exhibits dual roles in carcinogenesis, functioning as both a tumor suppressor and oncogene depending on context.
