7 Quantitative analysis method of non-human sialic acid using Cucurbituril7

摘要

In the present invention, after forming [CB[7] + sialic acid + NH ₄ +H] ²⁺ complex ions using the electrospray ionization method, the analytical performance of non-human sialic acid can be dramatically improved using mass spectrometry. It relates to a method for quantitative analysis of non-human sialic acid using cucurbituril [7]. When the quantitative analysis method of non-human sialic acid using cucurbituril [7] according to the present invention is used, there is an effect of enabling accurate relative and absolute quantification of sialic acid through a simple method, thereby reducing the analysis time and cost of non-human sialic acid. It can be drastically reduced.
