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.
