- What is our definition of water soluble? With very few exceptions, all biotin reagents are soluble in miscible organic solvents such as DMSO, DMF or acetonitrile. Typical protocols involve first dissolving the reagent at 10X the working concentration and then adding it to an aqueous reaction mixture. Organic solvents are not compatible with certain applications, and directly aqueous-soluble reagents are preferable in these situations. We classify reagents as water-soluble if they can be dissolved directly in water or aqueous buffers at greater than 1 to 5X the concentration needed for typical procedures.
