About TB500(Thymosin B4 Acetate)
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring 43-amino acid peptide found in virtually all mammalian cells. Thymosin Beta-4 acts as a multifunctional regulatory peptide comprising distinct bioactive regions within its structure: the N-terminal tetrapeptide (Ac-SDKP) mediates anti-inflammatory and antifibrotic activities, amino acids 1–15 inhibit apoptosis and promote cell survival, while the central actin-binding domain (amino acids 17–23, containing LKKTET) drives angiogenesis, cell migration, and wound healing in preclinical models.
Research applications for TB-500 encompass actin-sequestering protein interaction studies in cytoskeletal dynamics research, the characterization of the Ac-SDKP tetrapeptide's effects on TGF-β signaling and fibrosis-related gene expression, angiogenesis pathway analysis using in vitro models, and investigations of the peptide's nuclear localization and transcriptional regulatory effects. The compound is an important tool for studies examining thymosin family protein structure-activity relationships and peptide-actin binding mechanisms in controlled laboratory settings.

Lyophilized Research Peptides
This product is supplied in lyophilized (freeze-dried) form — a process that extends shelf life and preserves peptide purity and structural integrity during storage. No fillers, excipients, or preservatives are used in the lyophilization process. The lyophilized powder should be reconstituted with an appropriate research-grade solvent in a controlled laboratory environment prior to use in in vitro or preclinical assay systems.
