Inside our laboratory

The installation of a DNA sequencer at our research centre is enabling  researchers  to map the genomic sequence of a patient rapidly and efficiently on site. These findings can then be interpreted alongside existing tests such as MRI (magnetic resonance imaging) and EEG (electroencephalogram).Here's how DNA sequencing works.

Research associate Laura Hernandez uses a centrifuge as part of the process to extract DNA from 5-10ml of blood.




Research associate Bridget Maher measures the amount of DNA extracted from a blood sample.




DNA encoding the exome is loaded onto a microchip and placed in the DNA sequencer. DNA can be sequenced in two days but analysis takes longer.




DNA is measured at regular intervals throughout the sequencing process, as a control measure.




DNA sequences with suspected genetic variations are amplified to produce identical copies for analysis. These are loaded into a gel prepared with the help of a microwave oven.




DNA within the gel is photographed to confirm the amplification of DNA occurred correctly.
