FOXO4-DRI Reconstitution Calculator

For in vitro research use only · Not medical advice

Preset to a 10 mg FOXO4-DRI vial in 2 mL of diluent. A 10 mg vial in 2 mL yields 5 mg/mL. Use low-bind tubes for dilutions and keep solutions out of the light.

A 10 mg FOXO4-DRI vial reconstituted with 2 mL gives 5 mg/mL. Measuring 0.100 mL gives 500 mcg per portion — about 20 portions from the vial.

Choosing a diluent for FOXO4-DRI

Strongly basic — the sequence carries many arginine and lysine residues — so it dissolves readily in plain aqueous diluent without acidification. The same positive charge makes it stick to negatively charged surfaces such as untreated glass.

PrimarySterile water (USP grade)
Alternative 1Bacteriostatic water (0.9% benzyl alcohol)
Alternative 2Phosphate-buffered saline

Handling notes for FOXO4-DRI

  • Let the vial reach room temperature before opening.
  • Add diluent gently down the vial wall and swirl; do not vortex.
  • Use low-bind polypropylene rather than glass for dilutions — the cationic tail adsorbs to glass.
  • Protect solutions from light.

After reconstitution

StorageRefrigerate at 2-8 °C, protected from light, and aliquot for anything beyond short-term use.
Working windowCommonly worked with for 2-3 weeks at 2-8 °C in bacteriostatic water.
Freeze–thawAliquot on first reconstitution and freeze aliquots once; avoid repeated freeze–thaw cycles, which concentrate the peptide and salts at the ice interface.
