چکیده انگلیسی
Spherical DNA micro-assemblies appended with lactose units (Lactose-nucleo-cages, Lac-NC) are newly developed. DNA spherical assemblies self-assembled from suitably designed three oligodeoxyribonucleotides (ODNs) 1–3 were cross-linked by lactose-conjugated psoralen derivative 4. Confocal laser scanning fluorescence microscopy (CLSM) observation of Lac-NC shows that rhodamine labeled peanut lectin (Rho-PNA: a galactose-specific lectin) binds to lactose-modified nucleo-cages with higher affinity compared to that of unmodified nucleo-cages. Binding isotherm experiments indicated that the apparent affinity constant of Rho-PNA to Lac-NC was in the order of 105 M−1.
