TB-500 (Thymosin Beta-4 Fragment) Reconstitution Guide

This guide outlines how researchers reconstitute lyophilized TB-500 for laboratory use. It is reference information for preparing research solutions only. TB-500 is sold strictly for in-vitro laboratory research and is not for human or veterinary use, consumption, or diagnostic application.

What you need

Step by step

Example concentration

A common laboratory preparation is 10 mg reconstituted in 2 mL of diluent, which gives a concentration of 5 mg/mL. Concentration is simply compound mass divided by diluent volume — use more water for a lower concentration, less for a higher one. To compute the draw volume for any target amount, use the reconstitution calculator.

Storage and stability

Store lyophilized powder frozen at -20°C. After reconstitution, keep refrigerated at 2–8°C and use within the timeframe appropriate to your protocol (commonly a few weeks). Protect from repeated temperature cycling.

Analytical and COA

Purity is determined by HPLC and identity is confirmed by mass spectrometry. Each batch ships with a batch-specific certificate of analysis from an independent third-party laboratory; refer to the COA for lot-specific measured values. Endotoxin and sterility testing are not performed unless explicitly stated.

Frequently asked questions

How do you reconstitute TB-500?

Add bacteriostatic or sterile water slowly down the inner wall of the vial, then swirl gently until clear. Never shake. Example: 10 mg in 2 mL gives 5 mg/mL.

How much water should I use to reconstitute TB-500?

Any volume works — it only sets the concentration (mass ÷ volume). More water means a lower concentration. Use the reconstitution calculator to match a target amount per draw.

How is reconstituted TB-500 stored?

Keep reconstituted solution refrigerated and use it within the window appropriate to your protocol. Store unopened lyophilized powder frozen. See the storage section above for specifics.

Is TB-500 for human use?

No. It is sold strictly for in-vitro laboratory research and is not for human or veterinary use.
