Pulsed fields electrophoresis

Electrophoretic separation lies at the heart of polymerase chain reaction (PCR), isoelectric focusing (lEF), 2D gel electrophoresis, pulsed-field electrophoresis, capillary electrophoresis, and immunoelectrophoresis. 

Advances in experimental techniques, including pulsed-field gradient NMR, and theoretical methods, including volume averaging, macrotransport, and variational methods, that may lead to the resolution of a number of the fundamental issues in gel electrophoresis and to improvements in the practical application of electrotransport in polymeric media...

A combination of pulse field gel electrophoresis to separate large DNA restriction fragments, amplification by PCR, and detection with p53 cDNA probes has been useful to study chromosomal deletions and p53 mutations in colorectal cancers (Bl). 

Fig. 7. Frequency distribution of plasma Lp(a) concentrations (a) and apo(a) alleles (b) in three populations. Plasma Lp(a) levels were measured in 381 subjects by the sandwich ELISA technique apo(a) allele size (number of K-4 repeats) was estimated using pulsed-field gel electrophoresis and genomic blotting.

Figure 4.8 Patterns of smaldigested DNA of Staphylococcus aureus isolates on pulsed-field gel electrophoresis (PFGE). The isolates were obtained from four patients in diversely distant locations within the United States. Lane 1 = ATCC29213 (positive control), lane 2 = a methi-cillin-resistant S. aureus isolated from a patient in Georgia lane 3 = a gylcopeptide intermediate S. aureus isolated from a patient in Michigan, lane 4 = a methicillin-resistant S. aureus from the same patient in Michigan, and lane 5 = a glycopeptidet-intermediate S. aureus isolate from a patient in New Jersey.
