MOTS-c Reconstitution Calculator

A mitochondrial-derived peptide studied in metabolic regulation and exercise research. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted MOTS-c preparation, plus the mass-to-molar conversions for its stated molecular weight. Everything runs in your browser; nothing is transmitted or stored.

The pre-filled example, step by step

The inputs above are the neutral reference preparation this site uses everywhere the calculator appears: a 5 mg vial, 2 mL of bacteriostatic water, and a 250 mcg target amount. They are not a property of MOTS-c and not an amount anyone should draw — they exist so the arithmetic is visible before you change anything.

  1. Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for MOTS-c is approximately 1.15 mM at its stated molecular weight.
  2. Per syringe unit. A U-100 syringe divides 1 mL into 100 units, so one unit holds 2,500 mcg ÷ 100 = 25 mcg.
  3. Volume for the 250 mcg target. 250 mcg ÷ 2,500 mcg/mL = 0.1 mL, or 10 units on that syringe.
  4. Preparations per vial. 5,000 mcg ÷ 250 mcg = 20 preparations.

Mass and molar equivalents for MOTS-c

Derived from the molecular weight recorded on the MOTS-c entry: ~2174 g/mol — the entry states this as an approximate figure, so the equivalents below are approximate too. Concentration in molar units is what an in-vitro protocol is usually specified in.

Mass to molar conversions for MOTS-c at its stated molecular weight.
QuantityMolar equivalent
1 mg of MOTS-c460 nmol (0.46 µmol)
1 mcg of MOTS-c0.46 nmol
A 1 mg/mL solution0.46 mM (460 µM)

Molar amount = mass ÷ molecular weight. Figures are shown to four significant digits and are a unit conversion, not a measurement.

Reconstitution recorded for MOTS-c

Handling questions for MOTS-c

How should MOTS-c be reconstituted and stored?

MOTS-c is supplied as a white to off-white lyophilized powder, soluble in water, and is typically reconstituted with bacteriostatic or sterile water. Lyophilized peptide is stored refrigerated (2-8 C) or frozen for longer terms, with reconstituted solution kept refrigerated. A COA with HPLC purity and mass identity is standard.
