Provided is a method of preparing an acrylonitrile-based copolymer for a carbon fiber, which comprises: preparing a reaction solution including a monomer mixture comprising a sulfonate-based monomer represented by Chemical Formula 1, a carboxylic acid-based monomer, and an acrylonitrile-based monomer and an organic solvent; and subjecting the reaction solution to polymerization, wherein the monomer mixture comprises the sulfonate-based monomer represented by Chemical Formula 1 at 0.55 to 1.6 mol %.

Method of preparing acrylonitrile-based copolymer for carbon fiber

The present invention relates to a detection method for detecting a target RNA contained in a sample with high sensitivity by using nicking/extension chain reaction system-based isothermal nucleic acid amplification (NESBA) that uses activity of a cleavage enzyme and a DNA polymerase. The NESBA of the present invention is a new concept isothermal target RNA detection method that realizes higher amplification efficiency than the existing NASBA technology and is deemed to be utilizable as a new concept diagnosis technology that can replace conventional target RNA detection technologies.
