Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, developed from the tuftsin family and studied in neuropharmacology and stress-related research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Selank is investigated in research on anxiety regulation, stress response, emotional stability and neuropeptide signaling, and is commonly applied in cell-based and preclinical neuroscience studies. The lyophilized format ensures high stability and easy reconstitution for reproducible experimental dosing. Strict quality control is applied to every batch, and COA is available for specific batches on request. Keep the unopened product sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage avoiding repeated freeze-thaw cycles. Small and bulk orders are both welcome, and OEM and discreet neutral packing are offered. The tuftsin-derived heptapeptide is studied for anxiolytic-like activity and immune modulation, and researchers examine its effects on neurotransmitter systems and stress responses. Its short sequence supports clean synthesis and characterization. The lyophilized powder is supplied with HPLC purity data. Quality control covers raw-material inspection, synthesis monitoring and final-product testing, and batch records can be shared with buyers upon request. Packaging is designed to preserve lyophilized stability during international transport, including cushioning and secure sealing. We support small trial orders and large procurement programs, with consistent pricing and dependable lead times. Questions about product use, pricing or delivery are always welcome, and our team responds quickly through multiple channels.
