TB-500 (0.5mg/capsule), 60 Capsules
During our packaging transition, you may receive products with either our previous or updated label. Rest assured, the formulation, purity and quality remain exactly the same as per our standards.
TB-500 (Thymosin Beta-4) capsules provide an oral administration format for the 7-amino-acid fragment of Thymosin Beta-4 containing the LKKTET actin-binding motif, enabling oral route investigations alongside the lyophilized vial format. As with the injectable format, the active compound interacts with G-actin through its LKKTET motif, influencing actin polymerization dynamics, cytoskeletal organization, and cell migration–associated signaling pathways. Experimental investigations have examined TB-500 in relation to actin-regulatory mechanisms, molecular signaling networks, and pathway-specific processes involved in cytoskeletal biology. Research applications include oral versus parenteral comparative studies, actin cytoskeletal pathway investigation, cell migration signaling research, and mechanistic evaluation of actin-associated regulatory systems.

What is the research basis for the TB-500 capsule format?
TB-500 capsules provide an oral format for the Ac-LKKTETQ fragment of Thymosin Beta-4, the region containing the LKKTET actin-binding motif. Experimental studies have examined formulation-dependent characteristics, peptide stability properties, compound-processing mechanisms, and actin-associated signaling pathways.
What is the difference between TB-500 capsules and TB-500 vials for laboratory research?
They contain different compounds. The vials contain full-length Thymosin Beta-4, a 43-amino-acid peptide (CAS 77591-33-4). The capsules contain the 7-amino-acid Ac-LKKTETQ fragment (CAS 885340-08-9). Both include the LKKTET actin-binding motif, but they differ in size, structure and format, so researchers should choose based on which compound their study requires.
Does the capsule format of TB-500 change its mechanism of action compared to vial preparations?
No. The core mechanism involving G-actin interaction through the LKKTET motif is intrinsic to the TB-500 molecule and remains unchanged regardless of formulation format. Experimental differences between formats relate to formulation characteristics rather than the underlying molecular mechanism. This makes the capsule format useful for comparative investigations of actin-regulatory pathways, peptide-associated signaling processes, and formulation-dependent experimental variables.
