Various techniques are used for the enhancement of the solubility of poorly soluble drugs which include physical and chemical modifications of drug and other methods like particle size reduction, crystal engineering, salt formation, solid dispersion, use of surfactant, complexation, and so forth. Though i used hepes buffer at physiological salt concentration, i would like to know of any assay to test the solubility and stability of proteins . Solubility tests for unknowns it contains an acidic or basic functional group by testing with litmus paper form a carboxylate salt which is soluble in water .

Procedure for determining solubility of organic compounds the amounts of material to use for a solubility test are somewhat flexible use 2-3 drops of a liquid or approximately 10 mg of a solid. But for solubility of gas in liquids, an increase in temperature decreases solubility because gas evaporates as temperature increases 2 2 effect of pressure pressure unlike temperature has little effect on solutions unless the solute is a gas.
