Fill in all fields to see your results.
How to use
Enter Peptide Mass
The lyophilised mass stated on the vial, in milligrams. Use the label figure, not the assayed content, unless you are working from the batch certificate.
Enter Diluent Volume
The volume of bacteriostatic water or other diluent added to the vial, in millilitres.
Enter Target Amount
The amount of material the aliquot should contain, in micrograms or milligrams.
Read the Concentration
The result gives concentration in mcg/mL and the aliquot volume containing the target amount. Verify independently before relying on either figure.
Formula reference
Concentration
(Peptide mg × 1000) ÷ Water mL
= mcg / mL
Aliquot Volume
Dose (mcg) ÷ Concentration
= mL
