DNA Flow Technology

DNA Flow Technology provides the platform for rapid analyses in membrane-based reverse dot blot hybridization processes. This hybridization platform allows the DNA target molecules cross the membrane and direct the target DNA to the complementary capture probes that are immobilized on and inside the matrix pores.

This approach enables the reaction between the target DNA molecules in a three-dimensional porous environment rather than surface hybridization, allowing the reactions to be completed in seconds. It generates much higher signal intensities in a very short period of time, reducing reagent volumes and total processing time from hours to minutes, which represents an economic alternative for molecular diagnostic.
