TB-500 (Thymosin Beta-4) 5mg (43aa)

Introduction to TB-500 (Thymosin Beta-4) 5mg

TB-500 (Thymosin Beta-4) 5mg is the full-length, 43-amino acid synthetic representation of the endogenous protein found in nearly all mammalian cells. Unlike smaller fragments, this 43aa sequence encompasses the entire functional range of the Thymosin Beta-4 molecule. It is primarily recognized in the scientific community for its role as a major G-actin sequestering protein. At USA PEPTIDE SCIENCES, we provide this compound in its lyophilized form, ensuring that the complex secondary structures of the 43-amino acid chain remain intact for precise experimental use.

Research Overview: Pleiotropic Effects on Tissue Modeling

The research applications of the full-length TB-500 molecule are extensive due to its ability to upregulate cell-building proteins. By binding to G-actin, Thymosin Beta-4 inhibits polymerization and maintains a pool of actin monomers available for rapid filament assembly, which is a critical step in cellular motility.

Key areas of investigation for the TB-500 43aa sequence include:

• Angiogenesis and Endothelial Migration: Studying the formation of new blood vessels from pre-existing vasculature in vitro.

• Dermal Repair Mechanisms: Analyzing how the protein influences keratinocyte migration and collagen deposition.

• Myocardial Research: Investigating the potential for cardiac cell survival and migration following hypoxic modeling.

• Inflammatory Modulation: Researching the downregulation of various pro-inflammatory cytokines and the molecular signaling involved in reducing oxidative stress.

Quality Standards & Analytical Testing

At USA PEPTIDE SCIENCES, we adhere to the highest standards of analytical chemistry. Every 5mg vial of TB-500 (Thymosin Beta-4) undergoes exhaustive testing to ensure its identity and purity. We employ High-Performance Liquid Chromatography (HPLC) to verify that the purity exceeds 99% and Mass Spectrometry (MS) to confirm the exact 43-amino acid sequence. This rigorous verification process ensures that researchers receive a stable, contaminant-free compound that yields reliable and reproducible data.

Storage and Handling Requirements

To maintain the bioactivity of the TB-500 5mg vial, it must be stored away from light and heat. For long-term storage, the lyophilized peptide should be kept at -20°C. Upon reconstitution with a sterile diluent for laboratory assays, the solution should be kept at 2°C to 8°C. Because the 43aa sequence is sensitive to mechanical stress, researchers should avoid vigorous shaking of the vial and utilize gentle swirling to achieve complete dissolution.
