A near infrared fluorescence probe, lactose substituted zinc phthalocyanine, [2,9(10),16(17),23(24)-tetrakis((1-(β-d-lactose-2-yl)-1H-1,2,3-triazol-4-yl)methoxyl)phthalocyaninato] zinc(II), was synthesized via click reaction. Structural characterization and optical experiment demonstrated its
A simple and sensitive chromogenic microtitre plate assay for glycoprotein enzymes is described, using melanoma tissue plasminogen activator (t-PA) as a model enzyme. The assay is based on the binding of t-PA to immobilised lectin and quantitating the bound enzyme with plasminogen, fibrinogen
