Fragment analysis is used to describe genetic marker analysis experiments which rely on detection of changes in the length of a specific DNA Sequence to indicate the presence of absence of a genetic marker. In genetic marker analysis, the sequence of the gene is not directly analyzed. Genetic markers are usually polymorphic genetic sequences contained in or near an allele of interest, such as microsatellite or RFLP, which allow the chromosomal alleles to be distinguished.
At 1st BASE, we offer DNA Fragment Analysis service where fluorescently fragments are detected using our Applied Biosystems Genetic Analyzer and then interpreted using the GeneMapper® v 4.0 analysis software.
For analysis of fragments larger than 500bp, please send your enquiries to us.
