Thymosin Beta 4 Fragment 1-4 is the N-terminal tetrapeptide active fragment of thymosin β4. Third-party tested, USA-made, 99% purity peptide. Research use only (RUO).
Product Description
Thymosin Beta-4 Fragment 1-4 (TB4-Frag) is the N-terminal Ac-Ser-Asp-Lys-Pro sequence of thymosin β4. Research studies investigate modified actin-binding properties and cellular function compared to full-length TB4. Laboratory applications include cell migration pathway analysis, cytoskeletal organization studies, and tissue repair mechanism investigations in vitro.
The short fragment allows researchers to examine sequence-specific biological activities and structure-function relationships. Studies explore angiogenesis pathways, inflammation modulation, and cellular motility mechanisms. Research protocols utilize this fragment for comparative studies with full-length thymosin β4, examining minimal active sequences and peptide-protein interaction studies in controlled research settings.
