Subcloning with SalI and the E. coli vector pUC18 showed that the DNA also encoded a 31-kDa antigen. The cloned antigens were shown by immunoblotting to have the same molecular weight in E. coli as in C. pylori and to be present in all C. pylori strains. Antiserum was raised against the cloned polypeptides and found to react only with C. pylori when analyzed by dot blotting and indirect immunofluorescence. The cloned antigens were determined to be expressed from the pUC18 lac promoter. The.

NEB offers a selection of common cloning plasmids and DNAs for use as substrates (molecular weight = 2 x 10. 6). The small size of this plasmid makes it less susceptible to physical damage during handling. In addition, smaller plasmids generally replicate more efficiently in bacteria and produce larger numbers of plasmids per cell. As many as 500 copies of this plasmid may be present in a single E. coli cell. Plasmid pUC18 contains an ampicillin-resistance gene that. In molecular biology, restriction maps are used as a reference to engineer plasmids or other relatively short pieces of DNA, and sometimes for longer genomic DNA. There are other ways of mapping features on DNA for longer length DNA molecules, such as mapping by transduction. One approach in constructing a restriction map of a DNA molecule is to sequence the whole molecule and to run the. As the number of reaction cycles increases, the molecular weight of the product increases accordingly. The length of telomeric DNA obtained by 14 cycles (lane 4) is moderate, and thus it was selected as the starting materials for the next step. A base 'A' was added to the 3′ end of the PCR product by Taq DNA polymerase. After purification, the products were ligated with T-Vector, and the.

The high molecular weight, soluble aggregation of ca. 33 SXT-Exo protein monomers is most likely an artefact due to heterologous over-expression in E. coli, and is probably not biologically relevant. Consequently, in all subsequent biochemical assays, the concentrations of the SXT-Exo and lambda-Exo proteins were reported in terms of moles of trimers, as this is most likely the active form of. The enzyme was purified by ion exchange, hydroxylapatite and gel permeation chromatographies, and exhibited an apparent molecular weight of 80 kDa on SDS-polyacrylamide gel electrophoresis. Chitobiose and 6 more substrates, including beta-N-acetyl galactosamine glycosides, were hydrolyzed by the recombinant chitobiase, indicating its putative classification as an hexosaminidase [EC 3.2.1.52.
