NextGen-O2k Scientific developments

The revolutionary all-in-one instrument to conquer mitochondrial disease.

WP2: Scientific developments

Abstract

The aim of this workpackage is to test measurement conditions for the newly developed modules and the development of specific applications.

Determination of optimal Q-sensor measurement conditions
Determination of optimal measurement conditions for the PB-Module
Development of protocols for scientific, pre-clinical and algal biotechnology applications
Data handling and quality control

Achievements

Project Year 1: During testing in the first project year, optimal measurement conditions were determined for using the Q-sensor with a variety of biological samples. Simultaneously testing began of the beta version of DatLab. New SUIT protocols were developed for general, pre-clinical, and algal biotechnology applications. A focus has also been given to internal and external quality control measures.

Project Year 2: During the second project year, measurement conditions and protocols were optimized for the PB- and Q-Modules with a variety of biological samples. Additionally, the NADH-Module for evaluation of the NADH-pool in physio-pathological conditions was integrated in the NextGen-O2k. Testing of modules for the DatLab8 software were conducted and improvements applied. Moreover, SUIT protocols for general, pre-clinical, and algal biotechnology applications were developed. Quality control was maintained during the second period of project, an important factor in the development of the NexGen-O2k instrument and relevant protocols.
