Anti-p21 (FL) Antibody

Raised in rabbit against the full-length p21 protein, this unconjugated polyclonal antibody targets p21 (CDKN1A), a cyclin-dependent kinase inhibitor central to cell-cycle arrest, the DNA-damage checkpoint, and senescence signaling. Antibodies.com supplies the reagent as a 100 µl vial at 1 mg/mL in PBS with 0.1% sodium azide and 50% glycerol, ready for direct-labeling or secondary-detection workflows.

The antibody is validated for Western blot, immunohistochemistry, and immunofluorescence on Human, Mouse, and Rat samples, supporting proliferation, apoptosis, and tumor-suppressor studies in which endogenous p21 levels are tracked after genotoxic stress, oncogene induction, or drug treatment. Store the vial at -20 °C and divide into smaller aliquots to limit freeze-thaw cycles of the glycerol stock.
