DNA analysis, performance of polymerase chain reactions, clinical assays for pH, enzymes, proteins, oxygen etc., trace pollution monitoring and other sorts of biological analyzes are at the focus of recent developments [5]. Another reference lists environmental monitoring (including speciation), clinical monitoring, and quality control in production processes as applications of pTAS equipment in chemical analysis [30].

The same concept of volumetric in situ heating by microwaves was also exploited by Larhed and coworkers in the context of scaling-up a biochemical process such as the polymerase chain reaction (PCR) [25], In PCR technology, strict control of temperature in the heating cycles is essential in order not to deactivate the enzymes involved. With classical heating of a milliliter-scale sample, the time required for heat transfer through the wall of the reaction tube and to obtain an even temperature in the whole sample is still substantial. In practice, the slow distribution of heat... 

Apart from the traditional organic and combinatorial/high-throughput synthesis protocols covered in this book, more recent applications of microwave chemistry include biochemical processes such as high-speed polymerase chain reaction (PCR) [2], rapid enzyme-mediated protein mapping [3], and general enzyme-mediated organic transformations (biocatalysis) [4], Furthermore, microwaves have been used in conjunction with electrochemical [5] and photochemical processes [6], and are also heavily employed in polymer chemistry [7] and material science applications [8], such as in the fabrication and modification of carbon nanotubes or nanowires [9]. 

Rolling circle amplification (RCA) is an alternative method to polymerase chain reaction it is also a generic amplification technique that can be used in antibody assays. Using a replication process similar to that used by viruses, RCA allows the recognition,... 

Polymerase chain reaction (PCR) The process by which a specific sequence of DNA can be amplified (copied many times) in vitro. It requires a pair of primers and template DNA, thermostable DNA polymerase (e.g. Taq polymerase), deoxynucleotide triphosphates and a thermocycler. The process can amplify large... 

Such renaturation or annealing of complementary DNA strands is an important step in probing a Southern blot and in performing the polymerase chain reaction (reviewed in Chapter 7). In these techniques, a well-characterized probe DNA is added to a mixture of target DNA molecules. The mixed sample is denatured and then renatured, When probe DNA binds to target DNA sequences of sufScient complementarity, the process is called hybridization. 

One of the in vitro (in the test tube) processes used to clone DNA is called the polymerase chain reaction (PCR). A vial in which PCR is to be carried out contains all the necessary components for DNA duplication the piece of DNA to be cloned large quantities of the four nucleotides, A, T, C, G large quantities of a primer sequence, a short sequence of about 20 nucleotides synthesized by the primase enzyme and DNA polymerase.To conduct the process, the vial is hrst heated to 90-95°C for 30 seconds to separate the two DNA chains in... 

Fig. 5. Selection scheme for the in vitro selection of RNA libraries. The RNA library is subjected to a selection criterion suitable for the enrichment of functionally active sequences. The few selected individual sequences are amplified by reverse transcription (RT) and polymerase chain reaction (PCR). The PCR-DNA is then subjected to in vitro transcription with T7 RNA polymerase. The resulting enriched and amplified RNA library can be used as the input for the next selection cycle. This process is repeated until active sequences dominate the library. At this point, individual sequences can be obtained by cloning and their sequence can be determined by sequencing...

Antibody coverage of the human proteome is estimated to be about 5 to 10% of all human proteins and isoforms (Valle and Jendoubi, 2003). A major bottleneck in the use of protein expression arrays is the lack of such a comprehensive set of these capture agents (Hanash, 2003). Since an equivalent of the polymerase chain reaction (PCR) process for mass amplification of low abxmdant proteins does not exist, the remaining library of proteome capture ligands will need to be generated by other means such as recombinant protein expression systems (Cahill, 2001). 

Slide-based microarray technology was first introduced by Schena etal. (1995). The processes and equipment for preparing (arrayer) and analyzing (laser scanner) microarray slides comprised a portion of Dari Shalon s thesis work at Stanford University. Polymerase chain reaction (PCR) products (cDNA probes) were attached to PLL-coated glass microscope slides. The... 

Recently, another interesting application of nitrilases has been demonstrated for the synthesis of pregabalin-the API of the neurophatic pain drug Lyrica. In this approach, the key step is the resolution of racemic isobutylsuccinonitrile (Scheme 10.8) [18], the process takes place with total regio- and stereoselectivity, and the (S)-acid is obtained and the (R)-substrate can be recycled under basic conditions. To improve the biocatalytic step, directed evolution was applied using the electronic polymerase chain reaction and in the first round of evolution a single C236S mutation led to a mutant with 3-fold increase in activity [19].
