Your Ad Here	High Throughput Approach in Molecular Marker Technology For genotyping a large number of entries by the most efficient molecular marker system (e.g. SSR and AFLP), high throughput approaches are absolutely necessary. This involves extraction of only a low quality DNA (suitable for PCR) in the minimum of time (using Matrix Mill or FastPrep Systems that are commercially available), followed by amplification through DNA Engine Tetrad (thermal cycler), and laser detection through fluorescent labelling and automated sequencing machines, preferably based on capillary electrophoresis. Robot operated automated pipetting stations can be another facility that would add to automation.
Scale-up and automation, however, become difficult for majority of molecular markers, since most of them are gel based. Therefore, SNPs involving non-gel based detection (permitting scale-up and automation) will be the markers of choice in future. A number of available non-gel based assays for the detection of SNPs have been briefly discussed in this chapter, but only through further use of these assays, we will know, which of these assays is cost effective and most suitable for high throughput genotyping.
However, in many of these non-gel based assays, MALDI-TYF MS can be utilized for discriminating between two alternative alleles of a SNP. Use of high density oligonucleotide arrays is another high throughput approach, which will be extensively used in future. It has been shown that upto 1000 samples can be genotyped in one reaction using microarrays and MALDI-TOF MS. As discussed above. TMHA DHPLC WAVETM DNA molecular platform comprising HPLC/capillary electrophoresis system is also being used by Transgenomics (USA) for automated screening involving SNP discovery and detection.
