Sample Purification with High Analyte Concentration
Once collected, samples must go through critical preparation steps to enable reliable diagnostic testing. In order to achieve the highest sensitivity, diagnostic tests require purified analytes – free from inhibitors – at a high concentration.
Porous materials offer controlled pore sizes, providing the necessary filtration to normalize sample viscosity and to remove inhibitors. The customizable porous matrix prevents clogging, ensuring a controlled flow, which becomes increasingly important within cartridge-based testing. In addition to removing inhibition, Porex solutions utilize pure materials with low non-specific binding to prevent inhibition from materials and maximize available analyte for optimal test sensitivity
Optional integrated chemistry can simplify workflows by eliminating additional steps to help treat and normalize samples, such as incorporating cell lysis into the filtration step. The structure of Porex materials allows a singular component to achieve multiple steps, reducing assembly cost and simplifying the user protocol. A component can be used as a filter, as well as room temperature reagent storage, providing quick rehydration of reagents and a controlled flow for easy mixing. The structure can also support clinical protocols, like nucleic acid amplification, by incorporating extraction chemistry to perform the analyte isolation process. In addition to supporting test chemistry and sample purification, materials play a vital role in supporting the preparation infrastructure. This includes flow control, venting to prevent contamination, and absorption to prevent leakage of excess sample and used buffer reagents. Whether at home, at the clinic, or in the laboratory, Porex solutions simplify protocols and enable high-sensitivity testing.
