Patent JP-H03127999-A (JP)
Title: Synthesis of oligonucleotide
Inventor: KATO KINYA
IPC: C12Q1/68
Filed: 1989-10-12
Abstract: PURPOSE:To efficiently obtain the subject oligonucleotide by synthesizing short oligonucleotides, coupling many single strand DNA by formation of partially double strand, synthesizing a single strand fragment using enzymes and separating the resultant single strand. CONSTITUTION:A pair of single strand oligonucleotides having a complementary sequence composed of six base pairs or more at 3' terminal are synthesized using a DNA synthesizer. The resultant pair of oligonucleotides are mutually bonded at the complementary part to form a partially double strand. In this case, the resultant double strand acts as the primer of the respective synthesized DNA. A double strand is then formed while synthesizing oligonucleotides having complementary sequences from 5' side to 3' side by reagents for specified polymerizations using the respective projecting single strand parts as the templates. The double stranded oligonucleotide obtained by the previous process is then separated into single strands to obtain the objective oligonucleotide.
