Transfer of small plasmid DNA fragments from polyacrylamide gels onto nitrocellulose paper

Abstract: The incorporation into a 7% polyacrylamide gel of a nucleic acid-specific photochemical reagent 4,5',8-trimethylpsoralen at a concentration of 1 mg/dl of acrylamide solution improves both the sensitivity and the efficiency of the transfer of plasmid DNA fragments from the gel onto nitrocellulose filters. This improvement allows detection by blot hybridization of DNA fragments as small as 57 bp long.

“…292 Currently, the Southern blot is used for the detection of PCR products and determination of the reaction specificity. 293 ± 295 Nitrocellulose filters 225,292,296,297 and nylon membranes 298,299 (less frequently, p-azidobenzoylcellulose 236 ) or dried gels following fractionation of NA fragments 300 are commonly used for the fixation of the nucleotide material. Sandwich blot is a promising approach to the analysis of NA in non-purified specimens containing proteins, polysaccharides and other components.…”
