TB-500 (Thymosin Beta-4) Peptide

TB-500, or Thymosin Beta-4, is a synthetic analog of the endogenous Thymosin proteins, which are considered ubiquitously present in cells. The peptide belongs to a widespread family of 16 related molecules considered to exhibit a high degree of sequence conservation and localization in the majority of the tissues and circulating cells. TB-500 was developed with the intention of sequestering and blocking actin polymerization in eukaryotic cells.


Other Known Titles: Thymosin Beta-4

Molecular Formula: C212H350N56O78S

Molecular Weight: 4963.506 g/mol

Sequence: Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-lle-GluLys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-LysThr-Glu-Thr-Gin-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-GluThy-lleGlu-Gin-Glu-Lys-Gin-Ala-Gly-Glu-Ser

TB-500 (Thymosin Beta-4) Research

TB-500, or Thymosin Beta-4 expression appears to increase four-six fold during early angiogenesis. Research suggests it may promote the growth of new blood cells from existing vessels, and thereby potentially mediate faster tissue repair.[1] Researchers point out that “Delineating the molecular pathways impacted by Tβ4 to promote vascular growth and remodeling may reveal novel targets for prevention … of vascular disease.” The actin-binding domain happens to be a short central stretch of amino acid. It appears to be involved in TB-500-mediated regulation of blood cell division, tissue repair processes, migration of endothelial cells and keratinocytes, and possibly also higher production of extracellular matrix-degrading enzymes.

TB-500 research suggests the peptide’s potential anti-inflammatory characteristics.[2] According to the research, “It acts by increasing angiogenesis and cell migration and is currently [studied in] wound repair.”  TB-500, unlike other naturally produced growth factors, may possibly support endothelial and keratinocyte migration. It also does not appear to bind to the extracellular matrix, and researchers suggest that its low molecular weight may help it travel comparatively long distances through tissues. Study findings typically hypothesize the action of the peptide may be to regulate the polymerization and function of actin.

  1. Jade Peterson

    Amazing products and value. Very fast response and shipping. I am very pleased with the experience

  2. Mason Webb

    One of the leading suppliers in peptides. Very qualitative products

  3. Parker Findlay

    The quantity variations of the same products are very helpful and nice

  4. Astrid Duncan

    Had the peptide I needed in stock. Appreciate the coupon code as well.

  5. Jenifer Smith

    Just placed an order yesterday. this morning received an email from their rep telling me they are out of stock of it at the moment but will place it as soon as it’s in. It’s slightly frustrating. Just glad someone reached out instead of leaving me wondering what happened to my order.

  6. Taryn Alvarado

    They have great response times, friendly staff, and most importantly knowledgable staff! They are trained to know their stuff!!

  7. Orion Quinn

    The whole process was quick and easy.

  8. Mario Salvado

    The peptides are typically always stocked. Rare I have encountered one out of stock when it’s time to rebuy.

  9. coleen mcelroy

    Taylor was able to help me place a big order for our lab site. They worked with me and let me know if there was any substitues for peptides that they had out of stock as well! Prices are one of the best I have found as well when shopping around.

  10. Harper Santos

    Purest peptides on the market right now.

  11. Nikkie Wong

    Peptides work well with my specific research. This was my first time purchasing so I will definitely revisit!

  12. Eitan Assil

    Very happy to have found Biotech. Peptides are sold at a great price and the service you recieve is probably the best I have ever gotten anywhere.

  13. Ace Brashear

    Appreciate the discount code you sent after my 10th purchase!!
