PURPOSE:To remove protein which is a harmful material in analysis thoroughly and easily from a blood serum sample, by adding a water-soluble org. solvent to the serum to produce the precipitate of protein, then adding a water absorbent further thereto. CONSTITUTION:A water-soluble org. solvent is added to a blood serum which is required to be deproteinized in order to be subjected to analysis such as determination of medicines in blood, determination of traces of hormones in blood, etc. to allow protein to precipitate. A water absorbent is then added to a soln. mixture of the serum and the org. solvent, to force the water in the soln. to be absorbed in the absorbent, thereby removing the water in the soln. The protein dissolved in the water is deposited and settled by such removal of the water, and the serum is deproteinized thoroughly; therefore, the decrease in the analytic accuracy by the harmful material of the protein is prevented in the analysis to be executed thereafter. |
