✦ Synopsis


A new method for the easy preparation of specific single-stranded DNA fragments is presented. Recombinant Ml3 DNA containing the strand complementary to the sequence of interest is made partially double-stranded by elongating a conventional Ml3 sequencing primer. Following linearization by enzymatic digestion downstream from the insert (relative to priming site), this DNA is coupled to diazotized paper through its single-stranded (vector) portion. Subsequent denaturation of the double-stranded region generates an immobilized template strand. Successive runs of primed syntheses of the (desired) complementary strand can be realized using the same template. The copies are easily isolated by release upon denaturation. DNA probes prepared by this method have proven to be valuable tools for gene analysis. Q 1987 Academic Press, Inc.

We have used M13 single-stranded DNA bound by uv to small pieces of nylon membrane for the synthesis of biotinylated single-stranded DNA probes. The labeling method requires a large fragment of DNA polymerase I and random hexanucleotides. There is no need for previous linearization of the template.
