TB-500 Fragment (17-23) – Premium Research Peptide

Discover TB-500 Fragment (17-23), also known as fequesetide or the active sequence LKKTETQ (amino acids 17-23). This compact synthetic peptide is derived from the key actin-binding domain of Thymosin Beta-4, representing the smallest fragment that preserves the parent protein’s essential biological activity.

Preclinical research has demonstrated that this powerful fragment binds directly to actin, the critical cellular protein responsible for maintaining structure, enabling movement (cell migration), and supporting replication. Through this interaction, TB-500 Fragment (17-23) influences key processes including:

•  Regulation of cell migration and cytoskeletal dynamics

•  Promotion of angiogenesis (new blood vessel formation)

•  Modulation of immune responses

•  Acceleration of wound healing and tissue repair

•  Reduction of inflammation and scar formation

•  Enhancement of musculoskeletal recovery

In various animal models, these mechanisms have been linked to improved tissue remodeling, faster recovery from injury, and potential benefits in regenerative signaling pathways.

This peptide arrives in a stable lyophilized (freeze-dried powder) form, ensuring maximum shelf life and integrity for your laboratory studies.

Note: This product is provided as a Lyophilized, research-grade powder and does not come in liquid form.
