By the early 1990s, the PCR technique with Taq polymerase was being used in many areas, including basic molecular biology research, clinical testing, and forensics. It also began to find a pressing application in direct detection of the HIV in AIDS.
Abstract. The solubility of fructose in waterâethanol and waterâmethanol mixtures and the saturated density of each solution at 20, 30, and 40 Â°C over a range of water mass percentage have been measured.Also, a new modification of the Wilson model has been proposed to describe solubility data satisfactorily.bstract.

All Answers (8) The folic acid is soluble in 1 M NaOH (50 mg/mL), methanol (slightly), and alkaline solutions. The free acid is only slightly soluble in water (0.01 mg/mL ) and is insoluble in aqueous solutions below pH 5.It is soluble in sodium bicarbonate or sodium hydroxide solutions.
