What Is TB-500?
TB-500 is a 43-amino acid synthetic peptide representing the active region of Thymosin Beta-4 (Tβ4). The sequence corresponds to amino acids 17-23 of the full protein, which has been identified as the primary actin-binding domain responsible for many of the protein's biological activities.
As an isolated peptide, TB-500 provides researchers with a focused tool for studying:
- Actin sequestration and cytoskeletal dynamics
- Angiogenic signaling pathways
- Cellular migration mechanisms
- Extracellular matrix interactions
Using TB-500 alone allows researchers to establish baseline activity and understand isolated pathway effects before investigating potential synergistic interactions. This approach is fundamental to rigorous experimental design in research peptide studies.
What Is a BPC-157/TB-500 Blend?
A BPC-157/TB-500 blend combines two structurally distinct peptides: BPC-157 (Body Protection Compound, 15 amino acids derived from gastric juice proteins) and TB-500 (43 amino acids from Thymosin Beta-4). This combination enables research into potential synergistic or additive effects.
The rationale for blend research includes:
- Investigating multi-pathway modulation
- Studying potential synergistic interactions
- Exploring complementary mechanisms of action
- Modeling complex biological scenarios
However, researchers should note that blend studies add complexity to experimental interpretation. Proper controls with individual components are essential for understanding whether observed effects are synergistic, additive, or antagonistic.

Frequently Asked Questions
What is the difference between TB-500 alone and a BPC-157/TB-500 blend?
TB-500 alone is a single 43-amino acid peptide fragment derived from Thymosin Beta-4. The blend combines TB-500 with BPC-157 (15 amino acids from gastric juice), allowing researchers to study potential synergistic effects between two structurally distinct peptides.
Why would researchers choose a peptide blend over single peptides?
Researchers may choose blends to investigate synergistic or additive effects between compounds with different mechanisms of action. However, single-peptide studies are essential for establishing baseline activity and understanding isolated pathway effects.
How are purity standards maintained in peptide blends?
Quality suppliers test each component separately before blending and may provide dual COAs or a combined analysis. Both components should meet ≥98% purity standards with mass spectrometry confirmation of identity.
What storage considerations differ between single peptides and blends?
Storage requirements are generally similar: lyophilized at -20°C, reconstituted at 2-8°C. However, researchers should verify stability data specific to blended formulations, as component interactions may affect reconstituted stability.
Are peptide blends available for research in Canada?
Yes, both individual peptides and blends are available from qualified Canadian suppliers. All products are labeled for research use only with appropriate documentation for laboratory applications.
