Protein-immobilized solid phase, and polynucleotide-immobilized solid phase, as well as nucleic acid recovery method

摘要

According to the present invention, the protein-immobilized solid phase which can perform efficiently the nucleic acid recovered from the solid phase, and the polynucleotides immobilized solid phase, as well as better nucleic acid recovery method efficiency is provided. Proteins immobilized solid phase in one embodiment of the invention, mRNA (23) and mRNA for the protein encoded by the mRNA (23) (33) is coupled via a nucleic acid linker (2) (23) - nucleic acid linker (2) - protein (33) complex, and a protein-immobilized solid phase comprising by being immobilized on a solid phase, wherein the nucleic acid linker (2), the light cleavage site (2c) and a solid phase binding It is characterized by having a portion (2b).
