TB-500

What is TB-500?

TB-500 is a peptide. It is a lab-made version of a natural protein called Thymosin Beta-4.

Thymosin Beta-4 plays a role in cell migration, meaning cell movement, and tissue studies. TB-500 works by changing the level of actin, a protein tied to cell structure and movement.

What researchers study it for

• Actin activity. Researchers study how it affects actin, a protein tied to cell movement.
• Blood vessel formation. Studies look at new blood vessel growth, called angiogenesis.
• Cell migration. Labs study how it affects cell movement toward damaged tissue in models.
• Tendon and ligament tissue. Research looks at how it affects tendon and ligament cells.
• Inflammation markers. Some studies measure inflammation markers in lab models.

What you get

One sealed glass vial of freeze-dried powder. It comes in different vial sizes.

How to store it

Before mixing, keep the freeze-dried powder in a cool, dry place. After you reconstitute it, meaning mix it with liquid, keep it in a fridge between 2°C and 8°C. Use bacteriostatic water to mix it. Use it within 30 days.

Words you might not know

• Peptide — a very small protein, made of amino acids joined in a chain.
• Actin — a protein tied to cell structure and movement.
• Angiogenesis — the growth of new blood vessels.
• Reconstitute — to mix a dry powder with liquid so it can be used.
• Bacteriostatic water — sterile water that stops bacteria growing in it.
