Abstract: Disclosed are compositions and methods that enable loop-mediated isothermal amplification (LAMP) of one or more nucleic acid targets without the need for conventional LAMP primer design customized to each target. A transduction reaction is performed upstream from the LAMP reaction. The transduction reaction generates a single stranded DNA (ssDNA) oligonucleotide when the target nucleic acid is present in the sample. The ssDNA generated in the transduction reaction functions as a required LAMP primer for a universal LAMP template. The ssDNA thus promotes the LAMP reaction. Analysis of the LAMP products can determine the presence of the one or more nucleic acid targets.

Abstract: A preparation method of Antrodia cinnamomea water-insoluble dietary fiber. After ethanol and water extraction, Antrodia cinnamomea wastes are dried and superfine-comminuted to obtain Antrodia cinnamomea waste powder. The waste powder treated with NaOH solution containing NaBH4 is extracted it twice to obtain two extracts. The two extracts are combined and an appropriate amount of glacial acetic acid are added for neutralization. The extracts are centrifugalized and precipitate is collected. After washing the precipitate with ultrapure water, the precipitate is dissolved with LiCl-DMSO. The precipitate that is insoluble in the LiCl-DMSO solution is dialyzed and freeze-dried to obtain the water-insoluble dietary fiber component ACA-IDK of Antrodia cinnamomea. The LiCl-DMSO solution is subjected to ethanol/DMSO fractional precipitation, and then the precipitate is collected and dialyzed. The water-insoluble dietary fiber component ACA-DK of Antrodia cinnamomea is obtained after freeze-drying.
