The present invention relates to a method of labeling a sugar chain, used for labeling a sugar chain contained in a biological sample, aimed at simplifying a process of isolating a sugar chain from a biological sample and labeling it, which includes (a) trapping a sugar chain in a sugar-trapping substance, which is a substance for specifically trapping a sugar chain from a biological sample; (b) washing the sugar-trapping substance having the sugar chains trapped thereon; (c) releasing the sugar chain from the sugar-trapping substance; and (d) labeling the released sugar chain, wherein the processes (a), (b), (c) and (d) are conducted sequentially in a single reaction vessel. |
