TB-500 (10mg)

TB-500 (10mg): Product Description

TB-500 is a commercial name associated with thymosin beta-4-derived research material. Published analytical research has identified commercial TB-500 as an N-terminally acetylated fragment corresponding to residues 17-23 of human thymosin beta-4, represented by the sequence Ac-LKKTETQ. However, the name TB-500 is not applied consistently across suppliers and may also be used for full-length thymosin beta-4 or other related constructs.

Controlled laboratory investigations involving thymosin beta-4-associated materials may examine actin binding, cytoskeletal organization, cellular migration and signaling connected with extracellular-matrix and tissue-model responses. Full-length thymosin beta-4 is known principally as an intracellular G-actin-sequestering peptide, but a fragment cannot automatically be assigned all properties associated with the complete 43-amino-acid protein.

Because the exact molecular specifications depend on the supplied construct, Molecular Edge should not publish a definitive molecular formula, molecular weight, CAS number or amino-acid count until the product's Certificate of Analysis confirms whether the vial contains full-length thymosin beta-4 or the Ac-LKKTETQ fragment.

This 10 mg presentation identifies the nominal quantity of research material in the vial. Sequence, identity, purity, acetylation status and measured molecular mass must be verified through the batch-specific Certificate of Analysis.
