Dulaglutide Reconstitution Calculator
A long-acting GLP-1 receptor agonist Fc-fusion referenced in comparative metabolic research. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted Dulaglutide 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 Dulaglutide and not an amount anyone should draw — they exist so the arithmetic is visible before you change anything.
- Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for Dulaglutide is approximately 0.04188 mM at its stated molecular weight.
- Per syringe unit. A U-100 syringe divides 1 mL into 100 units, so one unit holds 2,500 mcg ÷ 100 = 25 mcg.
- Volume for the 250 mcg target. 250 mcg ÷ 2,500 mcg/mL = 0.1 mL, or 10 units on that syringe.
- Preparations per vial. 5,000 mcg ÷ 250 mcg = 20 preparations.

Mass and molar equivalents for Dulaglutide
Derived from the molecular weight recorded on the Dulaglutide entry: ~59700 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.
| Quantity | Molar equivalent |
|---|---|
| 1 mg of Dulaglutide | 16.75 nmol (0.01675 µmol) |
| 1 mcg of Dulaglutide | 0.01675 nmol |
| A 1 mg/mL solution | 0.01675 mM (16.75 µM) |
Molar amount = mass ÷ molecular weight. Figures are shown to four significant digits and are a unit conversion, not a measurement.
Reconstitution recorded for Dulaglutide
Lyophilized Fc-fusion protein typically reconstituted with bacteriostatic water; refrigerate and protect from light after reconstitution.

Handling questions for Dulaglutide
How should research-grade dulaglutide be stored?
As an Fc-fusion protein it is temperature-sensitive; lyophilized material is stored cold, reconstituted with bacteriostatic water, kept refrigerated, and protected from light and freeze-thaw. Expect a COA with purity (commonly greater than or equal to 98%) and identity confirmation as the standard quality reference.
