TB-500 (Thymosin Beta-4) – Peptide Research Compound
TB-500 (Thymosin Beta-4) (43 aa) functions as a synthetic peptide that mirrors the natural protein present in mammalian cells. Researchers investigate its 43-amino-acid sequence because it interacts with actin, a protein that shapes cell structure, movement, and organization. This interaction makes the compound valuable for research in peptide science, actin regulation, and cell biology.
Scientists prefer TB-500 because it allows them to explore actin-related processes and wider biological functions. Actin provides the backbone of the cytoskeleton, so labs use this peptide to track balance, migration, and stability in cells. These projects give researchers deeper insight into how peptides influence health and resilience at the cellular level.
Each vial carries lyophilized powder, which protects stability during storage and transport. Researchers dissolve the powder into a solution before testing. They store the compound in a cool, dry place away from light. After mixing, they refrigerate it immediately, and for long-term storage, they freeze it at –20 °C to maintain integrity.
Simple Peptide offers TB-500 at pharmaceutical grade for research and development only. The compound serves laboratory purposes exclusively, not human or animal use. We do not provide dosing information, but laboratories rely on this peptide as a consistent tool for studying peptide activity, actin pathways, and cell organization.
