title: Solid-phase assembly of cow colostrum trypsin inhibitor gene.
abstract: A gene for cow colostrum trypsin inhibitor (CTI) was constructed from synthetic oligonucleotides using a novel method of solid-phase gene assembly. In the first step an anchor oligonucleotide was covalently bound to the CNBr-activated Sephacryl S-500 support. Next, triads or tetrads of separately annealed oligonucleotides were stepwise hybridized to the immobilized complementary sequence, with washing after each step. In the last step a linearized vector molecule was ligated to the assembled gene. The whole construct was released from the solid support with a restriction enzyme, circularized, and used for transformation, with a high yield of recombinant clones being obtained. The method represents a generally applicable approach to rapid and efficient assembly of extended DNA duplexes.
