摘要： A pH adjusting apparatus includes an electrolytic chip receiving a solution, an electrolytic chip loading station receiving the electrolytic chip, an input unit inputting electrolysis conditions, a control unit receiving the electrolysis conditions and controlling electrolysis performed in the electrolytic chip, and a display unit displaying the electrolysis conditions and a progress of the electrolysis. Thus, the pH of a solution can be adjusted easily and accurately, by precisely controlling a constant current, a constant voltage, and current and voltage application times, thereby enabling useful application in various biological assays such as cell lysis. Furthermore, the pH adjusting apparatus has small size and weight and can be operated for a long time after charging once due to low power consumption.

摘要： Provided is a method of isolating and purifying nucleic acids using an immobilized hydrogel or polyethylene glycol (PEG)-hydrogel copolymer. The method includes: immobilizing a functional group-containing hydrogel or PEG-hydrogel copolymer on a substrate; adding a mixed sample solution containing a salt and nucleic acids to the hydrogel- or PEG-hydrogel copolymer-immobilized substrate to bind the nucleic acids to the hydrogel or the PEG-hydrogel copolymer; washing the nucleic acid-bound hydrogel or PEG-hydrogel copolymer; and eluting the nucleic acids from the hydrogel or the PEG-hydrogel copolymer using an elution solvent. Therefore, binding and elution of nucleic acids can be performed even with no addition of a separate chemical substance, and an effect on a subsequent process such as PCR can be minimized. Furthermore, the amount and intensity for binding nucleic acids can be adjusted according to PEG concentration, and the presence of a hydrogel compound on a substrate enables patterning.
