P21 is a synthetic research peptide referencing the p21 (CDKN1A) cyclin-dependent kinase inhibitor, a cell-cycle checkpoint protein studied in DNA-damage response, proliferation control, and cellular senescence models. It is prepared by peptide synthesis and supplied strictly as a research chemical for in vitro and cell-culture investigation.
Real Peptides supplies P21 as a 5mg lyophilized multi-dose vial. Every batch is tested by an independent laboratory, and the certificate for the current lot is published in the lab results section before purchase, so the lot number on the vial can be matched to the posted document. Orders ship from Florida and California facilities within 24 hours. Purchasers confirm they are 21 or older and are buying for laboratory research use; the product is not for human or veterinary use.

p21 is a key cell-cycle regulatory peptide that lets labs explore cell-cycle arrest, DNA-damage response, and senescence pathways with precision. Each 5 mg vial delivers a ready-to-use peptide that reliably induces p21-mediated checkpoint activation in cell cultures—no extra factors, no guesswork. HPLC-verified at ≥ 99% purity, and endotoxin-screened (< 0.1 EU/mg), p21 gives you crisp, reproducible data every time.
