A new and fast method for preparing high quality lambda DNA suitable for sequencing.

Abstract

A method is described for the rapid purification of high quality lambda DNA. The method can be used from either liquid or plate lysates and on a small scale or a large scale. It relies on the preadsobtion of all polyanions present in the lysate to an "insoluble" anion-exchange matrix (DEAE or TEAE). Phage particles are then disrupted by combined treatment with EDTA/proteinase K and the resulting DNA is precipitated by the addition of the cationic detergent cetyl (or hexadecyl)-trimethyl ammonium bromide-CTAB ("soluble" anion-exchange matrix). The precipitated CTAB-DNA complex is then exchanged to Na-DNA and ethanol precipitated. The resultant purified DNA is suitable for enzymatic reactions and provides a high quality template for dideoxy-sequence analysis.

Identification of a component separated on Mono Q purification of Escherichia coli RNA polymerase as an NTPase.

Standard preparations of Escherichia coli RNA polymerase (RNAP) contain NTPase activity. High-performance anion-exchange chromatography on Mono Q has recently been used by Hager et al. [1990, Biochemistry 29, 7890-7894] to fractionate RNAP into holoenzyme (alpha 2 beta beta' sigma) and core (alpha 2 beta beta') forms, plus other protein components. We found that one of these components, of protomer size slightly larger than the sigma 70 subunit, has NTPase activity; it is efficiently separated on Mono Q, leaving transcriptionally active holoenzyme and core apparently free of NTPase activity. Because of the similarity in size with sigma 70, the NTPase component may escape detection by routine gel electrophoresis.

Physicochemical characterization of Escherichia coli. A comparison with gram-positive bacteria.

Eight Escherichia coli strains were characterized by determining their adhesion to xylene, surface free energy, zeta potential, relative surface charge, and their chemical composition. The latter was done by applying X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR). No relationship between the adhesion to xylene and the water contact angles of these strains was found. Three strains had significantly lower surface free energies than the other strains. Surface free energies were either obtained from polar and dispersion parts or from Lifshitz-van der Waals and acid/base parts of the surface free energy. A correlation (r = 0.97) between the polar parts and the electron-donor contributions to the acid/base part of the surface free energy was found. The zeta potentials of all strains, measured as a function of pH (2-11), were negative. Depending on the zeta potential as a function of pH, three groups were recognized among the strains tested. A relationship (r = 0.84) was found between the acid/base component of the surface free energy and the zeta potential measured at pH = 7.4. There was no correlation between results of XPS and IR studies. Data from the literature of XPS and IR studies of the gram-positive staphylococci and streptococci were compared with data from the gram-negative E. coli used in this study. It appeared that in these three groups of bacteria, the polysaccharide content detected by IR corresponded well with the oxygen-to-carbon ratio detected by XPS.

Chromatographic separation of oligodeoxynucleotides with identical length: application to purification of oligomers containing a modified base.

A general procedure is described for separation and purification of oligodeoxynucleotides of identical length but different base composition, in particular, of oligomers containing modified bases such as 4-substituted thymines and 6-substituted guanines, using an anion-exchange column (either Mono Q or NucleoPac). The modified oligomers can be well separated from the analogous oligomers containing unmodified thymine or guanine under the basic conditions of the chromatography. The effects of oligomer length, base composition, and lipophilicity on the separation are discussed. A general rule which can be used for prediction of the order of elution of different oligomers and for estimation of tautomeric form of a modified base in the oligomer is presented.
