Description
TB-500 / Thymosin Beta-4 Technical Overview
Thymosin Beta-4 (Tβ4) is a naturally occurring 43-amino-acid peptide involved in the regulation of actin dynamics and cellular processes associated with cell migration.
TB-500 is a commercial designation often associated with Thymosin Beta-4-related research peptides. However, it can refer to different molecular forms, including fragments rather than full-length Tβ4.
Published research involving full-length Thymosin Beta-4 includes investigations of G-actin binding, cytoskeletal organization, cell motility, and experimental tissue injury models.
Results from these studies cannot automatically be attributed to a truncated TB-500 preparation.
