VIP reconstitution calculator
VIP ships as 5 mg, 10 mg vials 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.
- Concentration

Concentration = peptide mass ÷ diluent volume. Molarity = (mg/mL ÷ g/mol) × 1000. Research use only.

What the numbers mean for VIP
VIP has a molecular weight of 3326.83 g/mol (C147H238N44O42S). So 5 mg is about 1.5 micromoles, whatever volume you dissolve it in. At 2.5 mg/mL that is 0.751 mM.
Each vial holds only powder, from 5 mg up to 10 mg, 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 VIP?+
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 VIP 5 mg in 2 mL?+
2.5 mg/mL, which is the same as 2.5 µg/µL. With a molecular weight of 3326.83 g/mol that is 0.751 mM.
Which VIP vial sizes does the calculator cover?+
The ones we sell: 5 mg, 10 mg. Pick a chip or type any other mass.
Where does the VIP molecular weight come from?+
The reference value on the product's Specifications tab, 3326.83 g/mol. The observed mass for the vial you receive is on its own lab report, which the QR code on the vial opens.
