TB-500 Description

TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring 43 amino acid peptide found in virtually all mammalian cells. Thymosin Beta-4 acts as a multifunctional regulatory peptide comprising distinct bioactive regions within its structure: the N-terminal tetrapeptide (Ac-SDKP) mediates anti-inflammatory and antifibrotic activities, amino acids 1-15 inhibit apoptosis and promote cell survival, while the central actin-binding domain (amino acids 17-23, containing LKKTET) drives angiogenesis, cell migration, and wound healing.

TB-500 Peptide Research

Thymosin Beta-4 is a versatile peptide with applications across various therapeutic areas, including liver disease, ocular health, tissue repair, cardiovascular health, and anti-aging. Its ability to promote cell survival, reduce inflammation, and enhance tissue regeneration makes it a promising candidate for future research applications.

Tissue Repair and Regeneration

Tβ4 is involved in several biological processes that contribute to tissue repair and regeneration. It promotes cell migration, blood vessel formation, cell survival, and stem cell maturation, which are crucial for wound healing and tissue regeneration¹. It also demonstrates anti-inflammatory properties, downregulating inflammatory chemokines and cytokines, and resolving inflammation through autophagy².

Tβ4 has shown promising results in cardiac tissue repair, particularly following myocardial infarction. It activates resident epicardial progenitor cells, promotes cardiomyocyte survival, and enhances cardiac function by improving coronary neovascularization and modulating inflammation³.

In the CNS, Tβ4 regulates neurogenesis and promotes the repair of nerve tissues by supporting angiogenesis, wound healing, and stem cell differentiation. It also has anti-apoptotic and anti-inflammatory effects, which are beneficial in treating traumatic and neurological brain injuries⁴.

Tβ4’s regenerative properties extend to other organs, including the kidney, liver, and intestines, where it aids in tissue preservation and repair⁵.

Cardiovascular Applications

In cardiovascular research, Tβ4 has been shown to enhance the therapeutic efficacy of stem cells in ischemic conditions. It promotes angiogenesis and cell migration, which are crucial for repairing ischemic tissues.

Studies have demonstrated improved blood flow and reduced tissue loss in ischemic hindlimb models when Tβ4 is used in combination with stem cell therapy⁶.

Anti-Aging and Regenerative Therapies

Tβ4 is also being investigated for its potential in anti-aging therapies. It has been shown to promote cardiac cell survival and improve heart function after injury. The peptide’s ability to reactivate embryonic programs and enhance vascularization suggests it could play a role in reversing aging processes and promoting organ regeneration⁷.

Liver Disease and Ferroptosis

Thymosin Beta-4 has shown promise in treating non-alcoholic fatty liver disease (NAFLD) by inhibiting ferroptosis, a type of cell death. In a study using a rat model, Tβ4 improved liver inflammation and lipid metabolism, increased antioxidant levels, and reduced reactive oxygen species accumulation⁸.

This suggests that Tβ4 could be a novel strategy for NAFLD treatment by targeting the GPX4-mediated ferroptosis pathway.

Ocular Health and Bacterial Keratitis

Tβ4 is being explored as an adjunct treatment for bacterial keratitis, a severe corneal infection. It has been shown to reduce inflammation and promote wound healing in the cornea, enhancing the efficacy of antibiotics like ciprofloxacin⁹.

This dual action of reducing inflammation and promoting healing makes Tβ4 a potential therapeutic agent for improving outcomes in microbial keratitis.

Certificate of Analysis (COA) for Every Batch

A Certificate of Analysis (COA) is a document that verifies a compound’s identity, purity, and batch quality through independent laboratory testing. Every compound from BioLongevity Labs ships with a COA tied to its specific batch, so researchers can confirm exactly what they received before it enters a protocol.

Each COA reports results from third-party laboratory analysis, including:

• High-performance liquid chromatography (HPLC) for purity, typically confirmed at 99% or higher
• Liquid chromatography mass spectrometry (LC-MS) for molecular identity and mass confirmation
• Sterility and endotoxin screening where applicable
• Chemical contaminant and residual solvent checks

COAs are sourced from independent certified labs rather than in-house testing alone, giving researchers a verifiable record of molecular integrity for each batch. All compounds are supplied for research use only.
