Retatrutide (LY3437943) is a single lipidated peptide engineered to act on three receptors at once: the glucose-dependent insulinotropic polypeptide (GIP) receptor, the glucagon-like peptide-1 (GLP-1) receptor and the glucagon receptor. That triple-agonist profile makes it a reference compound for laboratory work on incretin and glucagon receptor signaling, and for comparing single, dual and triple agonism in cell-based models. Supplied as a lyophilized powder in 10, 20 and 30 mg vials.

Work out the concentration of a reconstituted lyophilized peptide and the volume of solution that contains a given amount. Concentration in mg/mL is numerically the same as µg/µL, which makes small aliquots easy to plan.

How the calculation works
Concentration is the mass of peptide divided by the volume of diluent: C (mg/mL) = mass (mg) ÷ volume (mL). Because 1 mg/mL equals 1 µg/µL, the volume that contains a target amount is simply the target in micrograms divided by the concentration: V (µL) = target (µg) ÷ C (mg/mL). The number of whole aliquots is the total mass in micrograms divided by the target, rounded down.
Worked example
A vial containing 10 mg of lyophilized peptide is reconstituted with 2 mL of bacteriostatic water. The concentration is 10 ÷ 2 = 5 mg/mL, which is 5 µg/µL. An aliquot of 250 µg therefore needs 250 ÷ 5 = 50 µL of solution, and the vial yields 10,000 ÷ 250 = 40 aliquots.
Accuracy notes for the lab
▪
The label states the gross fill. Net peptide content, the actual peptide after counter-ions and residual water, is usually lower. Use the net peptide value from the Certificate of Analysis when exact molar amounts matter.
▪
Pipette the diluent with a calibrated pipette rather than estimating from vial graduations, and let the cake dissolve fully before drawing an aliquot.
▪
Choose a volume that gives an easy-to-measure concentration. Very small aliquot volumes amplify pipetting error.
