What Is P21 Peptide?

P21 Peptide ranks among the reference compounds we supply for pre-clinical and in vitro research. P21, a synthetic peptide used in laboratory neurogenesis research. Researchers apply it in laboratory and in vitro research settings. Each unit meets a consistent synthesis standard. As with all our research compounds, we restrict distribution to qualified research personnel.

Research Applications

Early-stage research literature references P21 in the context of neurogenesis. This context differs entirely from the compound’s namesake cell-cycle regulator.

Researchers in neuropeptide research frequently cite compounds of this type when they study receptor binding, downstream signalling, and dose-response relationships in cell or tissue models. A consistent, well-characterised starting material makes it easier to compare findings across separate experiments. That said, solvent choice, handling temperature, and assay protocol can still introduce variability. Careful documentation at every stage therefore remains important.

Purity, Testing & Quality Assurance

We verify purity and identity independently for every batch, typically through HPLC or mass spectrometry, and supply a Certificate of Analysis on request. Independent verification gives researchers a way to confirm a compound’s specification before committing it to an experiment, rather than relying solely on our own testing. We also keep batch records on file, so any vial can be traced back to its original documentation.

Storage & Reconstitution

This product ships as a lyophilised powder, and researchers should reconstitute it with a solvent such as bacteriostatic water shortly before use. Once dissolved, the solution becomes more sensitive to room-temperature storage, so we recommend refrigeration and timely use. Preparing only the volume an individual experiment requires reduces exposure to freeze-thaw cycling, a known contributor to peptide degradation. In its unopened, lyophilised state, the compound stays considerably more stable when researchers store it as specified on the accompanying COA.

Usage Restrictions

This product serves laboratory and in vitro research only. It is not a medicine, and researchers must not use it for human consumption, animal consumption, diagnosis, or therapy. For independent chemical reference data, researchers can consult the PubChem compound database.
