Chromosomal and Genetic Variations

Large amounts of DNA are frequently required for use in detection assays and genomic analysis. The limited availability of DNA can be a critical obstacle to meeting research and clinical needs. DNA amplification methods are often required to generate sufficient material from small specimens or environmental samples with low DNA content. The MDA (multiple displacement amplification) reaction is increasingly the method of choice for many applications because of its extensive coverage of the genome, the generation of extremely long DNA products compared with older whole genome amplification methods and the high DNA yields, even from exceedingly low amounts of starting material. Remarkably, MDA enables genomic sequencing even from single microbial cells. Some of the uses of MDA and its strengths and limitations will be discussed.
