Preparation method of analytical sample, analytical method and kit for preparation of analytical sample |
| abstract |
The present invention relates to a method for preparing an analytical sample, an analytical method, and a kit for preparing an analytical sample, and provides a method for modifying sialic acid by a novel mechanism. A method for preparing an analytical sample is a method for preparing an analytical sample from a sample containing a sugar chain, and the preparation method includes an operation of performing an esterification reaction that converts sialic acid contained in the sugar chain into At least a part is used for esterification other than lactonization; the amidation reaction is performed by contacting the sample with an amidation reaction solution containing an optional sialic acid that has been reacted with the sialic acid modified by esterification. At least one compound selected from the group consisting of ammonia, amine, hydrazine, hydrazine derivatives, and hydroxylamine and salts thereof, the amidation reaction converting the esterification modification of sialic acid modified by esterification into amidation retouch. |
