TB-500

Description

For Research Use Only. This product is supplied exclusively for laboratory research and is not intended for human or veterinary use.

TB-500 Research Peptide

ZENTRA TB-500 is supplied as high-purity lyophilised research material in 5mg and 10mg formats. The listed material corresponds to the 43-amino-acid, N-terminally acetylated human thymosin beta-4 sequence.

Important terminology: “TB-500” is a research-market name that is not used consistently across the scientific literature. The sequence and molecular mass shown here correspond to full-length N-acetylated thymosin beta-4, and the cited studies below concern thymosin beta-4 rather than an undefined short fragment.

Technical Specifications

Independent Batch Testing

Every current ZENTRA TB-500 batch is independently tested and records an HPLC purity result above 99%. The batch number on the product label can be checked against the corresponding third-party report in our Batch Verification and COA Centre. Researchers should consult the individual report for the exact analytical methods, result and testing date for their supplied batch.

Thymosin Beta-4 Research Context

Thymosin beta-4 is an actin-binding peptide investigated in experimental models of cytoskeletal regulation, endothelial-cell migration and extracellular wound signalling. Primary laboratory studies have examined directional migration of human endothelial cells, the importance of its actin-binding motif to angiogenic activity, and NF-κB signalling in stimulated corneal epithelial cells.

Those findings are model-specific and do not prove a human clinical outcome. Researchers should also avoid treating every product sold under the TB-500 name as chemically interchangeable; sequence and analytical identity must be checked batch by batch.

Storage and Handling

For long-term storage, keep unopened lyophilised material at approximately -20°C. For short-term laboratory storage, maintain at 2-8°C. Protect the vial from light, moisture and repeated temperature changes. Use appropriate laboratory handling procedures and consult your institutional protocol before preparing research solutions.

TB-500 Research FAQs

What sequence does this TB-500 product contain?

The listed material is the 43-amino-acid N-acetylated thymosin beta-4 sequence shown in the specification table.

Is TB-500 the same name used in research papers?

Not usually. Scientific papers generally use “thymosin beta-4” or “Tβ4”. TB-500 is a market designation and can be used inconsistently, which is why the sequence and COA matter.

Which sizes are available?

This product is available as 5mg and 10mg of lyophilised research material.

What research areas have examined thymosin beta-4?

Published studies include actin sequestration, cell migration, endothelial signalling and wound-model biology. These are experimental findings, not evidence of an approved treatment.

How is purity verified?

Every current batch is independently HPLC tested above 99% purity with online batch-level COA verification.

Is this product intended for human or veterinary use?

No. It is supplied strictly for laboratory research and analytical purposes.
