Description

TB-500 5 mg

Buy TB-500 5 mg for laboratory research, supplied as lyophilized powder in one boxed 3 mL vial.

It is a single-compound product, separate from blends that combine TB-500 with other ingredients.

The TB-500 supplied in this product is full-length, N-acetylated thymosin beta-4: a 43-amino-acid peptide identified by CAS 77591-33-4.

Choose the amount and formulation

The alternative TB-500 10 mg listing is available for comparison. Check the product and batch records for the selected size; a larger labeled amount does not establish different purity or a different research effect.

On a blend listing, the total amount includes more than one compound. Compare its composition and individual amounts rather than treating the blend total as the quantity of TB-500. This powder listing is also a different presentation from a capsule, spray or prepared solution.

TB-500 and thymosin beta-4

This listing uses the full-length thymosin beta-4 identity. The terminal form is N-acetylated with a free-acid C-terminus; its reference sequence contains 43 amino acids.

A 2012 analytical study identified a different, acetylated seven-residue fragment in the preparation it examined. That fragment study explains why the TB-500 name alone is insufficient when comparing products or experimental methods. It does not characterize the full-length material listed here.

Match the documentation to the vial

Open COA & Documents to review the available product files and batch reports. For a sequence-specific experiment, match the full-length reference identity above to the experimental method. Lot reports provide separate evidence about the tested sample and the measurements performed.

Check the report’s product and lot, the methods performed, and whether each result concerns identity, chromatographic purity or measured content. Keep the 5 mg label separate from any measured batch result. The 3 mL container capacity is not a solution concentration or an instruction to add that volume of solvent.

Use handling and storage information applicable to the supplied material and laboratory method. Fixed preparation conditions or biological claims taken from another supplier’s product do not establish those properties for this vial.
