摘要:
A method is provided herein, the method includes : applying a sample comprising target nucleic acids to a sample application zone of a substrate; and flowing a nucleic acid amplification reaction mixture across a length of the substrate through the sample application zone to amplify the target nucleic acid forming a nucleic acid amplification product; wherein the target nucleic acid having a first molecular weight is substantially immobilized at the sample application zone and wherein the amplification product having a second molecular weight migrates away from the sample application zone. An associated device is also provided.

A method of drying a biological sample disposed on a substrate is provided. The method comprises providing the substrate comprising a sample loading area and a heat source; activating the heat source for generating heat; heating the substrate at least above 65° C.; and drying the biological sample. A device for storing sample is also provided, wherein the device comprises a substrate for biological sample-storage; and a heating component that generates heat to maintain a temperature of at least above 65° C. The heating component may contain one or more reagents, wherein the reagents generate heat to maintain a temperature of at least above 65° C.
摘要:
In accordance with the present disclosure, a method for extracting genetic material from a biological sample stored on a solid medium is provided. The method includes obtaining the solid medium, wherein the biological sample is applied on the solid medium, and the solid medium includes chemicals that lysed the biological sample and preserved the genetic material. The method also includes electroeluting the genetic material directly from the solid medium to a subsequent medium.
摘要:
A method is provided herein, the method includes: applying a sample comprising target nucleic acids to a sample application zone of a substrate; applying an aqueous buffer to the sample application zone of the substrate to washes away one or more inhibitors present on the sample application zone; and applying an isothermal nucleic acid amplification reaction mixture to the sample application zone to amplify the target nucleic acid to form a nucleic acid amplification product. The target nucleic acid having a first molecular weight is substantially immobilized at the sample application zone and wherein the amplification product having a second molecular weight.
