Thymosin Alpha-1 reconstitution calculator

Thymosin Alpha-1 ships as a 5 mg vial of lyophilized powder. Pick the size, type the water volume, read the concentration. The molecular weight is already filled in, so the molar result is there too.

What the numbers mean for Thymosin Alpha-1

Thymosin Alpha-1 has a molecular weight of 3108.3 g/mol (C129H215N33O55). So 5 mg is about 1.61 micromoles, whatever volume you dissolve it in. At 2.5 mg/mL that is 0.804 mM.

The vial holds 5 mg of powder and no diluent. Add bacteriostatic water down the inside of the glass, swirl, and do not shake. The reconstitution guide covers the handling; this page covers the arithmetic.

Common questions

How much water do I add to a 5 mg vial of Thymosin Alpha-1?+

Any volume that gives a concentration you can measure easily. 1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL, 5 mL gives 1 mg/mL. The peptide amount stays 5 mg whatever you add.

What is the concentration of Thymosin Alpha-1 5 mg in 2 mL?+

2.5 mg/mL, which is the same as 2.5 µg/µL. With a molecular weight of 3108.3 g/mol that is 0.804 mM.

Where does the Thymosin Alpha-1 molecular weight come from?+

The reference value on the product's Specifications tab, 3108.3 g/mol. The observed mass for the vial you receive is on its own lab report, which the QR code on the vial opens.
