Choosing a diluent for ARA 290

A short, hydrophilic linear peptide that dissolves readily in aqueous diluent without acidification. Solutions are clear and colourless.

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

Handling notes for ARA 290

  • Reach room temperature before opening the vial.
  • Add diluent gently down the vial wall; do not vortex.
  • Use low-bind labware at low working concentrations to limit adsorption.

After reconstitution

StorageRefrigerate at 2-8 °C and use promptly.
Working windowCommonly worked with for 2-4 weeks at 2-8 °C in bacteriostatic water.
Freeze–thawAliquot on first reconstitution; the short backbone tolerates a freeze better than folded proteins but repeated cycles still concentrate solutes at the ice interface.
