Hydroxyethyl-modified agarose reduces the number of hydrogen bonds between chains and can melt and solidify at lower temperatures than standard agarose. The ext
DNA fragments recovered from agarose gels, such as PCR products or digested DNA fragments, are resistant to further digestion. The reason for this resistance is
DNA prepared by this method is suitable for agarose gel electrophoresis, Southern blotting, subcloning, genomic library construction, PCR, or other methods that
Yeast DNA can be prepared by digesting the cell wall and lysing the resulting protoplasts with SDS, and several milligrams of yeast DNA can be reproducibly prep
The genes of many eukaryotes contain far more DNA than a single recombinant can hold. This is especially true for most chromosomes. Therefore, it is necessary t
Nucleic acids in agarose gels can be detected by staining under UV light at a wavelength of 300 nm. Two methods for staining nucleic acids in agarose gels are i
The following describes a reaction for labeling a 10 pmol high specific activity oligonucleotide. Labeling of different amounts of oligonucleotides can be accom
This protocol describes the separation of radiolabeled oligonucleotides from unadulterated radiolabeled material by quantitative differential precipitation with
When a λ phage arm is attached to an exogenous genomic DNA fragment, two parameters must be taken into account: the molar ratio of the phage arm to the potenti
A method for identifying and isolating specific recombinants from λ phage libraries was established early in the history of molecular cloning by Bemon and Davi
