<p>A method for the preparative recovery of electrophotetically resolved mRNA fractions from the matrix of the electrophoretic resolution, comprising applying to the matrix a carrier sheet of derivative cellulose or nitrocellulose bearing a plurality of residues selected from the group of polyuridylic acid and polythymidylic acid residues, cutting said carrier sheet into strips each of which holds an mRNA fraction and eluting an mRNA fraction from any desired strip.</p> |
