What is TB-500 (Thymosin Beta-4)?
TB-500 is a catalog name used for thymosin-beta-4-related research materials. This catalog lists 5mg and 10mg vials. The name alone does not establish the supplied peptide's exact sequence.
Listed vial contents: 5mg / 10mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.
Which identity should I verify?
The exact supplied construct remains unconfirmed. Full-length thymosin beta-4 and the Ac-LKKTETQ fragment are distinct. Match sequence, molecular weight and analytical identity to the original lot document; do not use the catalog's parent-peptide CAS or mass as confirmation.
What mechanisms are being studied?
Full-length thymosin beta-4 interacts with actin, a protein involved in cell structure and movement. Researchers examine its role in cell migration and tissue responses. Those findings must not automatically be attributed to a different fragment.
What are the research questions?
- Actin-associated cell behavior
- Cell migration and tissue-response models
- Comparing full-length thymosin beta-4 with defined fragments
What does the published work describe?
Malinda and colleagues' 1999 paper studied wound healing with thymosin beta-4 in a preclinical model. Goldstein and colleagues' 2012 review discusses the parent peptide's properties and clinical research context. Neither reference establishes equivalence between full-length thymosin beta-4 and an unspecified product labelled TB-500. Esposito and colleagues' 2012 analytical paper identified an N-terminal acetylated fragment in material labelled TB-500. That finding illustrates why sequence verification matters; it does not identify this inventory.
What could future research explore?
Thymosin-beta-4 research raises questions about tissue repair and formulation-specific applications. Future work must identify the tested construct and distinguish parent-peptide findings from fragment findings before comparing results.
These are research directions, not established applications of the product sold here.
What are the limits of this evidence?
Evidence for the full-length parent peptide is not evidence for every TB-500-labelled material. Neither a catalog name nor a study of another formulation establishes the effectiveness, safety or analytical identity of this vial.

How should I check lot documentation?
Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.
How is TB-500 (Thymosin Beta-4) handled in the lab?
For TB-500 (Thymosin Beta-4), record the product code TB, selected strength and lot before opening. Follow the material-specific safety data sheet and laboratory SOP, with appropriate gloves, eye protection and containment. For a documented dry preparation, let the sealed vial equilibrate before opening to reduce condensation; minimize time open and use clean, compatible vessels.
Choose a solvent for TB-500 (Thymosin Beta-4) from the documented sequence or chemical identity, salt form and assay requirements. Test a small portion first and record pH, solvent composition and clarity. Do not assume one diluent works for every research material; include a solvent-only control and establish compatibility before using the stock in an assay.
For TB-500 (Thymosin Beta-4), calculate mass concentration as measured material mass divided by final solution volume. Calculate molarity only with a documented molecular weight for the supplied chemical form; no usable molecular weight is established by the blank catalog field. Where available, use matched-lot net content rather than treating chromatographic purity as a mass correction. Record both stock concentration and subsequent dilution factors.
Use the documented storage conditions for the supplied TB-500 (Thymosin Beta-4) form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
A TB-500 (Thymosin Beta-4) laboratory protocol should record identity, product code TB, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.

Quality & Verification
TB-500 (Thymosin Beta-4) has a catalog purity specification of ≥99%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements. A blank field means no result is reported, not zero or passed. A purity percentage alone does not establish identity, sterility or suitability for human use.
