摘要
Isotachophoresis (ITP) can be employed to simultaneously focus the target and ligand of an assay into the same ITP focus zone. The target and ligand can bind to each other in the ITP focus zone, and then the resulting bound complex can be detected (e.g., by fluorescence). The sensitivity of this approach can be greatly increased by the enhanced concentration of both target and ligand that ITP provides in the focus zone. Since ITP can be performed quickly, the resulting assay is both rapid and sensitive. Markers of bacterial urinary tract infections have been experimentally detected at clinically relevant concentrations with this approach. MicroRNA sequences have also been profiled with this approach, which is clinically relevant because MicroRNA is expected to provide useful markers for disease. In one experiment, miR-122 in human kidney and liver was detected and quantified.
