Abstract
A sample preparation kit related to the present invention provides a significantly versatile analytical technique that is not affected by the diversity of antibodies, difference in species, matrix and the like. For preparing a sample to be used for detection of a monoclonal antibody through high-performance liquid chromatography-mass spectrometry (LC-MS), the kit includes a porous body for immobilizing a monoclonal antibody to be detected; nanoparticles with an immobilized protease; a reaction vessel for selectively digesting the monoclonal antibody by bringing the porous body and nanoparticles into contact; a buffer to be introduced into the reaction vessel along with the nanoparticles and porous body so that a protease reaction is carried out; and a filtration membrane to remove the porous body and nanoparticles after the proteolysis so as to extract the reaction product and the buffer.
