An amphiregulin-specific double-stranded oligo siRNA structure comprises hydrophilic and hydrophobic compounds bound to the amphiregulin-specific double-stranded oligo siRNA by a simple covalent bond or a linker-mediated covalent bond so as to increase the in vivo stability and intracellular delivery efficiency of the double-stranded oligo siRNA, and to nanoparticles composed of the oligo siRNA structures. The amphiregulin-specific double-stranded oligo siRNA structure can increase the stability of the amphiregulin-specific double-stranded oligo siRNA without impairing the function of the amphiregulin-specific double-stranded oligo siRNA, and at the same time, can efficiently increase the membrane permeability of the double-stranded oligo siRNA. Thus, when the amphiregulin-specific double-stranded oligo siRNA structure is used, the amphiregulin-specific double-stranded oligo siRNA can be efficiently delivered into cells even when it is administered at a relatively low concentration, so that it can be effectively used for the prevention or treatment of respiratory diseases.

Provided are an oligonucleotide marker and a method of identifying a material using the same. The oligonucleotide marker makes it possible to analyze a trace amount of the material with high precision within a short time, has improved solubility in an oily solvent, and can improve a detection method such that the oligonucleotide marker can be detected within 2 hours. The oligonucleotide marker can label various products, including oil products and petroleum products, works of art and collections, and can also be used to conduct criminal investigations.


A composition for hot-start reverse transcription reaction and a composition for reverse transcription PCR are disclosed. The composition is obtained by adding pyrophosphate and pyrophosphatase to an aqueous solution containing reaction buffer solution, MgCl


The present invention relates to a method for preparing a nucleic acid with high sensitivity, wherein a nucleic acid polymerase is used to add a terminator to the nucleic acid to be used for analysis prior to a nucleic acid polymerization reaction such as a PCR reaction, a real time quantitative PCR reaction, or the like, for detecting a trace of nucleic acid, such that a non-specific priming occurring competitively with an amplification reaction of a target nucleic acid may be basically eliminated, thereby precisely detecting only the trace of target nucleic acid and precisely measuring a concentration of the target nucleic acid.


A method of manufacturing a micro-chamber plate with a built-in sample, including: settling a micro-chamber plate for sample injection at a micro-chamber plate receiving part formed with an upper opening; disposing a cover for micro-chamber plate receiving part to cover the upper opening, the cover for micro-chamber plate receiving part having a provisional storing part and an auxiliary covering part connected with the provisional storing part and formed with a through-hole for auxiliary covering part; and manufacturing a micro-chamber plate with a built-in sample by putting the micro-chamber plate receiving part, on which the cover is disposed, into a centrifugal separator which can apply vacuum, applying centrifugal force and injecting a sample solution provisionally stored in the provisional storing part into the micro-chamber plate through a vessel communication part which is formed at the provisional storing part to be communicated with the micro-chamber plate receiving part.
