Method for the selective removal of proteins from biological samples using chemicals

摘要

This invention relates to compounds of formula (I) in a biological sample containing protein: ; [Formula I] ; [wherein, R ¹ , R ² , and R ³ are each independently a hydrogen atom or a substituted or unsubstituted an alkyl group having 1 to 6, a is an integer from 1 to 6 (provided that the amine contains two or more alkyl groups) and adding a nucleating protein substance (nucleating agent); Processing the mixture with a hydrophobic surface material; And a method of removing nucleic acid in the protein, while maintaining the biological sample comprising the step of separating the sample from the hydrophobic surface of the protein material is combined. According to the present invention a protein from a biological sample containing protein is efficiently removed, and the nucleic acid can be selectively removed by having the protein present in the sample.
