Next-Generation Sequencing and the Diagnosis of Disease
insights from industryJohn RossenProfessor of Medical MicrobiologyUniversity of Groningen
In this interview, News-Medical talks to Professor John Rossen of the University of Groningen, about his research into DNA sequencing and microbiology and how his work is benefitted by Tecan.
Could you start by giving our readers a brief overview of your background and the history of DNA sequencing?
I am appointed as a Professor at the University of Groningen and the University of Utah, School of Medicine. I am also currently employed at IDbyDNA, an organization that is designing and selling software to analyze metagenomics data.
Establishing a Method for Laser Diffraction Particle Size Analysis of Lactose Powder
Experiments were conducted to establish a laser diffraction-based method for the determination of lactose powder particle size.
This was accomplished using a Bettersizer 2600 equipped with a fully automatic dry dispersion system. This device enabled researchers to study the particle size measurement of lactose powders systematically.
The impact of different dispersion pressures on the particle size distribution measurement was investigated, and a study into the precision of the dry dispersion method was undertaken. A comparison of measurement results revealed that dry dispersion can control risks well and improve data correlation.
