Chloroquine is supplied as a lyophilized powder. For a 50 mM stock, reconstitute the 150 mg in 5.82 ml sterile dH2O. First add 1 ml dH2O to the tube containing the chemical, vortex, and dispense into a new, larger tube. Repeat this action two or three more times to transfer any residual material. Add additional dH2O to the new tube to bring the volume up to 5.82 ml. Filter sterilize into sterile tube. Utilize a syringe and 0.2 μm syringe filter to minimize sample loss.
Working concentrations and length of treatment can vary depending on the desired effect, but it is typically used at 25-100 μM for 12-48 hr.
Store lyophilized at room temperature or in solution at -20ºC, desiccated. Protect from light. In lyophilized form, the chemical is stable for 24 months. Once in solution, use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.
