External certification by NordVal confirms that results obtained by LactoSens®R are equivalent to the reference method HPLC.

The recently accepted NordVal International validation assures that LactoSens®R lactose biosensor assay kit performs with high accuracy and specificity down to detection limit of 0.008% lactose. All characteristics are found to be in compliance with claims, demonstrating equal performance with the reference method HPLC (ISO 2262 IDF 198).

External validation studies have been performed to prove that the biosensor assay kit LactoSens®R can be used to determine residual lactose in milk samples with a fat content of up to 36% as well as in fermented milk products like yoghurt, cream, sour cream and curd. Furthermore, it was approved that the sensor is also applicable to lactose-free flavored yogurts and milk drinks (e.g. coffee, cacao, fruits). In addition, it was verified that the sensors are stable for at least 3 days storage at 30⁰C.

The external certification by NordVal makes LactoSens®R the perfect choice for product release, process optimization and product development. More about LactoSens®R…

FFG Bridge Project started

DirectSens started a cooperation with the laboratory of Prof. Dietmar Haltrich at the VIBT BOKU for the project „StaREliS – Stabilisation of Redox Enzymes for long-term implantable Sensors”.

StaREliS aims to elucidate the deactivation mechanism of redox enzymes, which should serve as the basis for the development of stable enzymes for long-term biosensors.

The project is funded by a Bridge grant from the the Austrian Research Promotion Agency (FFG).

International Dairy Magazine appreciates NordVal validation

From the dairy industry point of view, IDM stresses the need for a precise, fast and easy method of on-site measurement of residual lactose – to bring it down to the recommended 0.01% lactose-free threshold. This has been made possible thanks to the technical breakthrough of LactoSens®. The recent NordVal validation of this method against the reference method for lactose determination allows dairies to easily integrate LactoSens® into their certified quality management system: This method’s high levels of accuracy, specificity, stability, and reliability have proven to be in line with the ISO 17025 standard.
