Synthesis of oligonucleotides on cellulose. Part II: Design and synthetic strategy to the synthesis of 22 oligodeoxynucleotides coding for gastric inhibitory polypeptide (GIP).

A solid-phase approach using trinucleotide building blocks and functionalized cellulose as solid support was used to synthesize the 22 oligodeoxynucleotides that constitute a totally synthetic gene coding for a 43 amino acid peptide. Gastric inhibitory Polypeptide. The overall strategy used for the design and synthesis of the oligomers is described.
