نبذه عن الكتاب:
1980s (1,2), capillary electrophoresis (CE) has been recognized for its potential to replace
slab-gel electrophoresis for the analysis of nucleic acids (3,4). In particular, the availability
of commercial instrumentation for CE over the last several years has made both the size
determination and quantitation of DNA restriction fragments or polymerase chain reaction
(PCR) products amenable to automation. Due to the same charge-to-mass ratio, the electrophoretic mobility of nucleic acid molecules in free solution is largely independent of
their molecular size (5). Therefore, a sieving medium is required for the electrophoretic
analysis of DNA fragments based on their size. Typically, two different principal types of
separation matrix are used. The first type of matrix is of high viscosity polymer (e.g.,
polyacrylamide) with a well-defined crosslinked gel in regard to the structure and size of
its pores. The second type of matrix is a noncrosslinked linear polymer network of materials such as, linear polyacrylamide, agarose, cellulose, dextran, poly(ethylene oxide), with
lower viscosity than the former type and with a more dynamic pore structure. Although the
first type of matrix is attached covalently to the capillary wall and may provide better
separation for small (sequencing) fragments, the second matrix format has the advantage
of being able to be replenished after each electrophoretic cycle. This typically extends the
lifetime of a capillary, prevents contamination of the system, avoids sample carryover and
allows the use of temperatures well above room temperature. Most matrices used in both
systems are tolerant to the addition of DNA denaturants. Many different media useful for
the separation of DNA have now become commercially available (6).
In summary, the application of CE for DNA related research is attractive for
numerous reasons:
