  • Publication number: 20160131644
    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.
