Temperature-gradient electrophoresis

Reciprocally, the growth on single C source significantly decreases the bacterial diversity. For example, in the rhizosphere soil of potato, a dramatic reduction in the number of ribotypes was found by temperature gradient gel electrophoresis (TGGE) after 48 h of incubation with single C source substrate in Biolog microplate wells (I46). [Pg.185]

Packed capillaries with a larger inner diameter may be useful in preparative separations. These will find an application in proteome research as a part of multidimensional separation systems that will replace 2-D gel electrophoresis. The preparative CEC will require solving of the problems related to heat dissipation since the radial temperature gradient negatively affects the separations, and sample injection. The fabrication of sintered frits in larger bore capillaries is also very difficult. However, in situ polymerized monolithic frits can be fabricated in capillaries of virtually any diameter [190]. [Pg.46]

FIGURE 3-19 Electrophoresis, (a) Different samples are loaded in wells or depressions at the top of the polyacrylamide gel. The proteins move into the gel when an electric field is applied. The gel minimizes convection currents caused by small temperature gradients, as well as protein movements other than those induced by the electric field, (b) Proteins can be visualized after electrophoresis by treating the gel with a stain such as Coomassie blue, which binds to the proteins blit not to the gel itself. Each band on the gel represents a different pro-... [Pg.93]

In another report, 2D separation was applied to resolve DNA duplexes. Three types of DNA duplexes (136-bp homoduplex, 339-bp heteroduplex, and 450-bp heteroduplex) were involved in a SNP study. First-dimension CGE separated the three types of DNA molecules. Subsequent temperature gradient gel electrophoresis (TGGE), which was an analogous counterpart to denaturing gradient gel electrophoresis, was used to resolve the duplexes to reveal SNP [669]. [Pg.186]

Natural convection generally has a negative effect on separation its countercurrent motion leads to the disruption and smearing of component zones. Electrophoresis is particularly subject to such convective flow because the passage of electrical current generates heat that in turn sets up temperature gradients in the electrophoretic medium. [Pg.72]

Figure 37-12 An example of temperature-gradient capillary electrophoresis (TGCE).The PCR fragments are denatured and annealed before the electrophoresis (see diagram in Figure 37-10). Only one peak is visible for the PCR fragment of a normal homozygous specimen, whereas all four possible duplexes are visible and separated from each other in a heterozygous mutant specimen.The shape of the elution profile (rather than the elution time) is used to compare unknowns with control samples.
