About P21 (P021)
P21, also written P021, was developed in the laboratory of Khalid Iqbal at the New York State Institute for Basic Research in Developmental Disabilities. It is built from a biologically active region of ciliary neurotrophic factor (CNTF) and carries a C-terminal adamantane group that increases lipophilicity and protects it from exopeptidases.
The design aimed to capture the neurotrophic activity of CNTF in a small, stable molecule.
Research context
P21 is studied in rodent models of neurodegeneration and aging for its effects on hippocampal neurogenesis, BDNF expression, synaptic markers and tau pathology.

P21 (P021): frequently asked questions
Is P21 related to the p21 protein?
No. P21 here is the CNTF-derived peptide P021. The cell-cycle regulator p21 (CDKN1A) is an unrelated protein that happens to share the name.
Which P21 (P021) presentations are listed?
One presentation is listed: 5 mg (P210). Each is packed 10 vials per box, and every presentation has its own specification page and product code.
