ACE-031 Reconstitution Calculator

A soluble activin receptor type-IIB fusion protein referenced in myostatin-pathway and muscle-research literature. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted ACE-031 preparation, plus the mass-to-molar conversions for its stated molecular weight. Everything runs in your browser; plan entries stay in this browser, with optional device-local saving and calendar export.

Syringe capacity

Whole administrations exclude dead space, handling losses and expiry. A calculated quantity is not a guarantee of usable supply. No rounding to a nearby syringe mark is performed.

Protocol schedule

Schedule an existing prescribed or approved protocol. This tool cannot determine how often you can safely take a peptide. Frequency, dose, reconstitution, storage and discard instructions must come from the product label and your clinician or pharmacist.

A separate worked example, step by step

This separate arithmetic example uses a 5 mg vial, 2 mL of bacteriostatic water, and a 250 mcg target amount. They are not a property of ACE-031 and not an amount anyone should draw — these figures only illustrate the arithmetic.

  1. Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for ACE-031 is approximately 0.03125 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 ACE-031

Derived from the molecular weight recorded on the ACE-031 entry: ~80 kDa (glycosylated ActRIIB-Fc homodimer) — 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 ACE-031 at its stated molecular weight.
QuantityMolar equivalent
1 mg of ACE-03112.5 nmol (0.0125 µmol)
1 mcg of ACE-0310.0125 nmol
A 1 mg/mL solution0.0125 mM (12.5 µM)

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

Reconstitution recorded for ACE-031

Supplied as a lyophilized biologic requiring reconstitution and cold-chain storage; handled like an antibody-type protein rather than a small peptide.

Handling questions for ACE-031

Why is ACE-031's large size relevant to research handling?

Because ACE-031 is a ~80 kDa glycosylated Fc-fusion protein rather than a sub-10 kDa peptide, it behaves like an antibody-type biologic: it has a long circulating half-life driven by Fc recycling and requires cold-chain handling. This distinguishes its stability and dosing-interval considerations sharply from small synthetic peptides.
