| 摘要 |
The present invention can be useful as an active ingredient of a composition or a kit for measuring or detecting glycoproteins, glycopeptides, glycolipids, sugar precursors or oligosaccharides having sialic acid sugar chains, containing a recombinant lectin specifically binding to sialic acid sugar chains, by providing: a method for producing a Polyporus squamosus-derived PSL1b recombinant lectin, which specifically binds to sialic acid sugar chains, from an Escherichia coli PSL1b strain (deposit number: KCTC12507BP) or a Pichia pastoris PSL1b strain (deposit number: KCTC12500BP); and a lectin produced thereby. |
