Latest Patents

Hammerschmidt's latest patents focus on a method for isolating extracellular nucleic acids using anion exchange particles. This invention pertains to methods and kits designed for isolating these nucleic acids from biological samples. A key finding of her research is that incorporating a polyoxyalkylene fatty alcohol ether into the binding mixture compensates for performance variations that may arise from differences in the anion exchange surface. This improvement is crucial as it addresses inconsistencies that can occur between different lots of anion exchange particles or during their storage. Furthermore, the inclusion of this ether results in higher purity of the obtained eluates, which significantly reduces inhibition in downstream reactions, such as PCR.
