TB-500 5MG

描述

Core Features
$\ge 98.5\%$ Ultra-High Purity Guarantee (Ultra-Pure SPPS Synthesis): This product is manufactured using high-standard automated Solid-Phase Peptide Synthesis (SPPS) technology. Given the long molecular chain of TB-500, trace impurities—such as truncated chains or mismatched amino acids—can easily arise during synthesis. We employ a precise C18 reversed-phase chromatography process with narrow fraction cutting to ensure that every vial in the standard 5mg package maintains a purity of $\ge 98.5\%$, providing a clean, interference-free matrix for your in vitro and in vivo academic research.
Actin Regulation and Cell Migration Mechanism (Actin-Sequestrating & Angiogenesis Model): As a key functional fragment of natural Thymosin $\beta_4$ ($\text{T}\beta_4$), TB-500 retains full G-actin binding activity. The molecule efficiently promotes the migration of endothelial cells and keratinocytes and accelerates the macro-regulation of angiogenesis. It serves as a “gold standard” model in the life sciences for studying angiogenic signaling pathways, myocardial remodeling, and the downregulation of inflammatory factors.
Superior 5mg Lyophilization Process (Advanced Lyophilization Lock): The 5mg peptide powder undergoes moisture sublimation at ultra-low temperatures ($-80^\circ\text{C}$) in a near-vacuum environment, resulting in a uniform, fluffy, snowflake-like crystalline solid. This process not only ensures excellent reconstitution—allowing for rapid, complete dissolution without precipitation or residue when mixed with BAC water—but also stabilizes the molecular conformation, significantly reducing the risk of thermal degradation during international transit or customs delays.

❄️ Storage Requirements & Comprehensive Cold Chain Protection
Laboratory Storage Protocol: Upon receipt, the product must be immediately stored—in its unreconstituted state—in an explosion-proof, research-grade ultra-low temperature freezer ($-20^\circ\text{C}$ to $-80^\circ\text{C}$), protected from light and moisture at all times. Storage in standard retail outlets or administrative offices lacking professional equipment is strictly prohibited. After reconstitution, aliquot and freeze according to your experimental plan to prevent denaturation of the peptide’s spatial conformation caused by repeated freeze-thaw cycles.
Pharmaceutical-Grade Cold Chain Shipping: Strict adherence to the platform’s “Shipping & Order Schedule.” For the 5mg TB-500, we utilize high-density, thickened foam containers paired with high-capacity, manufacturer-supplied cold packs for express delivery, ensuring the peptide molecules remain in a “locked-frozen” state of activity throughout transit.

📝 Scientific Compliance and Disclaimer (Research Limitations)
⚠️ Strictly For Research Use Only: This product (TB-500 5mg) is a chemical reagent intended for cutting-edge life science research. In strict adherence to global compliance standards, this product is restricted to academic research within university laboratories, research institutes, or corporate R&D centers (e.g., cell proliferation assays, monitoring of injury repair in animal models). Any unauthorized human clinical use (injection or oral administration), veterinary clinical application (such as wound spraying), or use as a performance-enhancing substance in medical or athletic contexts is strictly prohibited. This platform strictly enforces the verification of “End-Use Declarations.”
