Relative fluorescent quantitation (or quantitative fluorescence PCR (QF-PCR)) is a technique used in a variety of fragment analysis applications that requires accurate peak height comparisons across multiple samples. Applications that utilize this technique include screening for loss of heterozygosity (LOH) using microsatellites or SNPs, aneuploidy assays, and detecting large chromosomal deletions.

DNA Purification kit

DNA extraction is a critical first step in the experimental workflow of DNA Sequencing and Fragment analysis. The overall quality, accuracy and length of the DNA sequence read can be significantly affected by characteristics of the sample itself, and the method chosen for nucleic acid extraction. Ideal methods will vary depending on the source or tissue type, how it was obtained from its source, and how the sample was handled or stored prior to extraction.

Capillary Electrophoresis

During capillary electrophoresis, the products of the PCR are injected electrokinetically into capillaries filled with polymer. High voltage is applied so that the fluorescent DNA fragments are separated by size and are detected by a laser/camera system.
