AAT Bioquest-XFD488化學(xué)結(jié)構(gòu)與Alexa Fluor®488相同（Alexa Fluor™是ThermoFisher的商標(biāo)）。麥胚凝集素（WGA）是一種與N-乙酰-D-葡糖胺和唾液酸結(jié)合的凝集素。由于其生物學(xué)應(yīng)用，它是研究最多、最有用的凝集素之一。由于WGA與糖復(fù)合物結(jié)合，其衍生物和偶聯(lián)物被廣泛用于標(biāo)記細(xì)胞膜和纖維化瘢痕組織，用于熒光成像和分析。WGA的碳水化合物結(jié)合特異性針對(duì)β-1,4-GlcNAc連接的殘基序列，即殼聚糖。每個(gè)單體包含兩個(gè)相同的、不相互作用的結(jié)合位點(diǎn)，它們與3或4個(gè)β-1,4-GlcNAc單元互補(bǔ)。在所研究的單糖中，只有GlcNAc與WGA結(jié)合。ManNAc不結(jié)合，GalNAc只弱結(jié)合。WGA的XFD488共軛物相當(dāng)于WGA的Alexa Fluor®488共軛物。它表現(xiàn)出明亮的綠色熒光。XFD488 WGA綴合物與唾液酸和N-乙酰氨基葡萄糖殘基結(jié)合。
