Description

TB-500 (Thymosin Beta-4 Fragment)

TB-500 is a high-precision synthetic fragment of the naturally occurring protein Thymosin Beta-4. This specific 30-amino acid sequence is engineered to encompass the critical biological domains responsible for cellular signaling, actin sequestration, and chemotaxis. In the realm of advanced biochemical research, TB-500 is a primary focus for its role in promoting tissue repair, accelerating wound healing, and stimulating angiogenesis—the formation of new blood vessels. By interacting with G-actin, this peptide provides researchers with a stable model to study the complex mechanisms of cellular migration and extracellular matrix (ECM) remodeling.

Our TB-500 is synthesized in an ISO 9001:2015 certified and GMP-grade manufacturing environment. Utilizing state-of-the-art Solid-Phase Peptide Synthesis (SPPS) and multi-stage HPLC purification, we guarantee a chemical purity of ≥99%. This ensures that the 30-amino acid sequence is correctly assembled and free from truncated fragments or residual synthesis reagents, providing the high-fidelity data required for peer-reviewed academic and pharmaceutical studies.

Key Features & Quality Assurance

Pharmaceutical-Grade Lyophilization

Our proprietary vacuum-sealing process ensures the TB-500 powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure guarantees rapid, clear reconstitution and prevents the 30-amino acid chain from environmental degradation.

Structural Fidelity

Every batch undergoes strict Mass Spectrometry (MS) to verify the exact amino acid sequence and sequence integrity, ensuring maximum biological activity in research environments.

Reconstitution & Storage

Reconstitution Guide

• Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the TB-500 cake is at the base.

• Solvent: Reconstitute with Sterile Water or Sterile Saline (0.9% NaCl).

• Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is clear and transparent.

Storage Protocols

• Long-term: Store at -20°C (Maintains potency for up to 24 months).

• Short-term: Stable at 2–8°C for up to 3 months.

• Post-Reconstitution: Store at 2–8°C and utilize within 10-14 days.
