Overview
Pinealon is a synthetic tripeptide investigated for neuroprotective and antioxidant activity in CNS research. The peptide is studied for effects on neuronal survival, oxidative-stress markers, and circadian-axis gene expression in rodent and cell-culture models.
Each vial is lyophilized from acetate buffer, sealed under nitrogen, and shipped ~4 days from our lab.
Research applications
Neuronal-survival assays under oxidative stress, in-vitro Aβ-toxicity protection screens, and circadian-clock gene-expression studies.

Reconstitution
Allow vial to reach room temperature before opening (≥ 20 minutes). Reconstitute with 1.0–2.5 mL of sterile bacteriostatic water (0.9% benzyl alcohol). Inject solvent slowly down the inner wall of the vial; do not direct stream onto the lyophilized cake.
Swirl gently for 30 seconds. Do not vortex. Allow to dissolve for 5 minutes; clarity should be complete with no visible particulates.
Storage after reconstitution
Reconstituted solution is stable for 28 days at 2–8 °C in original vial. For longer storage, aliquot into low-binding tubes and hold at −80 °C; avoid repeated freeze-thaw cycles. Discard if turbidity, color change, or particulate matter is observed.
