Synthesis of the human insulin gene. Part IV. New synthetic deoxyribooligonucleotide adaptors and primer for DNA cloning and sequence analysis.
The chemical synthesis of four new deoxyribooligonucleotides to be used as adaptors in molecular cloning of DNA for expression studies is described. These are (i) start-adaptor, (ii) stop-adaptor, (iii) conversion adaptor to insert ribosomal binding site, and (iv) retrieving adaptor. We have also synthesized a 19-bases-long primer, 5'-TTGTAAAACGACGGCCAGT-3' to increase the speed of DNA sequence analysis and also demonstrated its application using single-stranded M13 DNa vector.
