Abstract: The present invention relates to a method for the detection of a protein including a histidine-tag using immunochromatography. The detection method of the present invention uses immunochromatography using the polymer particle fixed with the histidine-tag, wherein a histidine-tag specific antibody alone is used to detect a histidine-tag conjugated protein (recombinant protein) quickly without using a target protein specific antibody. This method is also efficient in detecting and quantifying the histidine-tagged protein included in the sample without using an additional apparatus but quickly and accurately.

Abstract: The present invention relates to a chabazite zeolite membrane with a controlled pore size and a production method thereof, wherein the sizes of pore space and pore mouth of the chabazite zeolite membrane are finely controlled through chemical vapor deposition. Through the chemical vapor deposition, defects present in the chabazite zeolite membrane are eliminated, and the pore size is effectively controlled. Thus, unlike hydrophilic membranes showing excellent CO2/N2 separation performance under a dry condition, the chabazite zeolite membrane with a controlled pore size according to the present invention has a hydrophobic surface, and thus can maintain excellent CO2/N2 separation performance even under a wet condition. Accordingly, the chabazite zeolite membrane of the present invention can effectively capture carbon dioxide from nitrogen under various environmental conditions.
