Batch documentation

Review documentation for the product and variant you are purchasing. A reference specification, a research publication and an individual batch certificate are different sources. Certificate results are accessed with your order details; if documentation is available on request, contact support before relying on it.

Laboratory handling

Reconstitution

Laboratory procedure: allow the closed vial to reach room temperature, disinfect the septum and slowly transfer the diluent against the inner wall of the vial. Do not shake; gently swirl the vial until fully dissolved. Record the volume, diluent and date in the batch log.

Storage

Sealed vial of lyophilized material: store at −20 °C, protected from light and moisture. Avoid repeated freeze-thaw cycles of reconstituted material; aliquot when the experimental design permits.

Protective equipment

Handle in a clean work area with a lab coat, nitrile gloves and eye protection. Dispose of vials, tips and sharps according to the laboratory waste procedure.

Research references

The combination was examined in an exploratory rat study with a four-week follow-up; the cited sources do not establish its effects in humans. The sources also differ on whether TB-500 designates full-length thymosin beta-4 or a fragment (PMID 41966639, PMID 42542926). The commercial name alone does not resolve that identity.
