Calculator FAQ

How do I reconstitute lyophilised peptides?+
Add bacteriostatic water slowly to the vial, letting the powder dissolve against the glass. Use the calculator to choose a convenient concentration for your research sample size per your SOP.
Which syringe scales does the calculator reference?+
The calculator references U-100 insulin syringes, where 1 mL = 100 units (marks). Each unit mark represents 0.01 mL (10 microL).
How do I convert mg to mcg?+
1 milligram (mg) = 1,000 micrograms (mcg). Use the Unit Converter tab for quick conversions between mg, mcg, and grams.
What is a blend calculator used for?+
The blend calculator determines the concentration of each individual peptide in a multi-peptide blend vial. Enter the total blend mass and each component mass to calculate individual concentrations.
