High-throughput and rapid nucleic acids detection method based on capillary microarrays

摘要

A high-throughput and rapid nucleic acids detection method based on capillary microarrays comprises the steps that firstly, microarray containing a number of hydrophilic and vertical micro-channels is fabricated by capillary assembling, casting and machining, and the outer surface of the capillary array is coated with super-hydrophobic Ultra-Ever Dry paint; secondly, different primer sets are individually loaded into the micro-channels and air-dried to adhere them on the inner surface, and then the microarray is anchored into a reaction tube; thirdly, the reaction mixture is introduced into every microchannel at once through capillary force by a special designed sample-loading adaptor, and then the amplification reaction is performed in the temperature control device; and finally, the fluorescence can either be measured continually during the reaction for real-time detection or be recorded once in the end for endpoint detection. Moreover, the products can also be recovered for other use later.
