摘要:
A liquid chromatography device includes a sample inlet valve to which a sample to be analyzed is introduced, and a trap valve fluid-communicating with a solid phase extraction column and a reverse phase liquid chromatography column. The device further includes a solvent dividing unit dividing flow of a solvent discharged from the sample inlet valve into the first solvent inlet port and the second solvent inlet port of the trap valve. The liquid chromatography device improves resolution and increases reproducibility by allowing the sample injecting direction and the sample eluting direction to be opposite to each other.

摘要:
Disclosed are nanoparticles for use in the isolation of peptides, a method for producing the nanoparticles, and a method for the isolation of peptides using the nanoparticles. The nanoparticles comprise magnetic nanoparticles and thiol-specific functional groups as first functional groups bound to the surfaces of the magnetic nanoparticles to selectively capture cysteine-containing peptides. The nanoparticles allow highly selective isolation of target peptides in a simple and rapid manner. Therefore, the nanoparticles can be applied to research on the treatment of diseases such as cancers.

Methods of killing mosquito larvae and controlling an adult mosquito population by using α-mangostin, 3,6,8-yrihydroxy-2-methoxy-1,7-bis(3-methylbut-2-enyl)xanthen-9-one, or a salt, solute, hydrate or solvate thereof. Mosquito larvae are killed by contacting a lethal dose of α-mangostin with mosquito larvae. Adult mosquito populations are controlled by treating a mosquito larvae population with a lethal dose of α-mangostin.
