TB-500 (Fragment) is a synthetic, N-acetylated version of LKKTETQ, the actin-binding active site within thymosin beta-4, studied for its role in cell migration and tissue signaling in rodent models. Philp, Goldstein & Kleinman, 2004 (PMID 15037013) documented thymosin beta-4's involvement in angiogenesis and cell migration research. For Research Use Only. Not for human consumption. (54 words)

Description
About this peptide
About This Compound
TB-500 is a synthetic version of the seven-amino-acid sequence LKKTETQ (residues 17-23), the active actin-binding site within the naturally occurring 43-amino-acid protein thymosin beta-4. The way a single gear can be removed from a larger mechanism and still turn on its own, this short fragment reproduces one specific functional site of the parent protein — the domain implicated in actin sequestration and cell motility — without carrying the rest of the molecule's structure.
Research Context
Ho et al., 2012 (J Chromatogr A, PMID 23084823) characterized the N-acetylated LKKTETQ peptide as the key component of TB-500 preparations, developing an analytical method to detect the compound and its metabolites in biological samples. Philp, Goldstein & Kleinman, 2004 (Mech Ageing Dev, PMID 15037013) documented the parent protein thymosin beta-4's involvement in angiogenesis and cell migration in rodent tissue models. Sosne et al., 2010 (FASEB J, PMID 20179146) mapped the specific functional sites within thymosin beta-4, identifying the LKKTETQ actin-binding domain as distinct from the molecule's other active regions.

Shipping & Storage
Handling this material
Shipping
Orders ship within 24 hours. Delivered via USPS Priority or standard FedEx unless expedited shipping is selected at checkout. Tracking is emailed on dispatch and mirrored in your account.
In-transit handling
Lyophilized vials are shelf-stable and ship at ambient temperature. Storage in our warehouse is cooled; shipment does not require refrigeration.
Long-term storage
Lyophilized vials are shelf-stable at ambient temperature; refrigeration (2–8°C) extends shelf life. Refer to the batch-specific Certificate of Analysis for material-specific storage guidance. Once reconstituted, follow the storage instructions on the batch COA. Not for human or animal consumption.
Returns
Because these are research-grade biologics, we cannot accept returns on opened vials. Damaged-in-transit shipments are replaced at no cost within 7 days of delivery.
