Selank-5mg

描述

Core Product Highlights
$\ge 98.5\%$ Ultra-High Purity Guarantee (Ultra-Pure SPPS Synthesis): This product is manufactured using high-standard Automated Solid-Phase Peptide Synthesis (SPPS) technology. During chromatographic purification, we rigorously eliminate all incompletely condensed peptide fragments and trace biochemical impurities. For the standard 5 mg packaging, every single vial is guaranteed to achieve an exceptional purity level of $\ge 98.5\%$, providing a pristine matrix—free from any biochemical interference—for your in vitro and in vivo academic research.
Classic Heptapeptide Conformation and Enzyme-Resistant Design: Selank (Sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro) is engineered by fusing a Pro-Gly-Pro tripeptide fragment to the C-terminus of the endogenous human tetrapeptide, Tuftsin. This precise molecular engineering design significantly enhances its resistance to enzymatic degradation within tissue fluids. It currently serves as a pivotal tool for scientists investigating the inhibition of cerebral enkephalin-degrading enzymes, the modulation of the GABAergic nervous system, and anti-stress behavioral models.
Superior Lyophilization Process with “Full-Lock” Activity Preservation: The 5 mg peptide powder undergoes water sublimation at an ultra-low temperature of $-80^\circ\text{C}$ within a near-vacuum environment. The resulting crystalline structure presents a uniform, delicate, snowflake-like morphology; this not only ensures excellent reconstitution properties (allowing for rapid dissolution with Bacteriostatic Water) but also deeply “locks” the peptide’s spatial molecular conformation, thereby maximally preventing thermal degradation during international transit.

❄️ Storage Requirements & Comprehensive Cold Chain Protection
Laboratory Storage Mandate: Upon receipt, the product—while remaining in its lyophilized (unreconstituted) state—must be immediately stored in an ultra-low temperature, explosion-proof, research-grade freezer maintained between $-20^\circ\text{C}$ and $-80^\circ\text{C}$. It must be kept shielded from light and moisture at all times. It is strictly prohibited to store this product in ordinary retail settings or administrative offices lacking specialized equipment.
Pharmaceutical-Grade Cold Chain Direct Shipping: We strictly adhere to this platform’s “Shipping and Order Scheduling Policy.” The 5 mg Selank product is shipped via express courier in high-density, extra-thick foam packaging, combined with the manufacturer’s original high-capacity cold packs. This ensures that the peptide molecules remain in a “frozen-locked” state—preserving their full biological activity—as they traverse vast distances to reach you.
