What TB-500 is in this catalog

TB-500 in this catalog is a thymosin beta-4 fragment. It is evaluated for actin-binding and cell-migration kinetics in vitro. This page does not describe athletic, veterinary, or human applications.

How each lot is documented

Biscayne Science holds a hard purity floor of at least 99% by HPLC on every compound, with mass-spectrometry identity confirmation. Endotoxin is screened to under 0.25 EU/mg by accredited LAL assay, and each batch is tested for sterility. Testing is done by an accredited third-party lab. A lot-matched Certificate of Analysis is available on request and is tied to the lot printed on the vial, not a representative sample from another batch.

A certificate reports those research results for that lot. It is not a representation that a material is safe or suitable for any use in humans or animals. The request path is the Certificate of Analysis page.

Catalog formats

The catalog lists 10 mg and 20 mg vials of lyophilized powder. Reconstitution supplies are not included. Multi-vial tiers are on the shop listing.

Endotoxin for the lot is reported on the Certificate of Analysis, under 0.25 EU/mg by accredited LAL assay. The powder is not described as a sterile finished product. Each batch is tested for sterility, and that result is part of the lot report.

Vials ship as lyophilized powder in Type I borosilicate glass. Orders ship within 7 business days of payment, with free U.S. shipping on orders over $300. Biscayne Science was founded in Miami, along Biscayne Bay.
