    • Methods and compositions are described for immobilizing anti-ligands, such as antibodies or antigens, hormones or hormone receptors, oligonucleotides, and polysaccharides on surfaces of solid substrates for various uses. The methods provide surfaces covered with caged binding members which comprise protecting groups capable of being removed upon application of a suitable energy source. Spatially addressed irradiation of predefined regions on the surface permits immobilization of anti-ligands at the activated regions on the surface. Cycles of irradiation on different regions of the surface and immobilization of different anti-ligands allows formation of an immobilized matrix of anti-ligands at defined sites on the surface. The immobilized matrix of anti-ligands permits simultaneous screenings of a liquid sample for ligands having high affinities for certain anti-ligands of the matrix. A preferred embodiment of the invention involves attaching photoactivatable biotin derivatives to a surface. Photolytic activation of the biotin derivatives forms biotin analogs having strong binding affinity for avidin. Biotinylated anti-ligands can be immobilized on activated regions of the surface previously treated with avidin.
    • 描述了用于在固体底物的表面上固定抗配体如抗体或抗原,激素或激素受体,寡核苷酸和多糖的方法和组合物用于各种用途。 这些方法提供了覆盖有笼式结合构件的表面,其包括在施加合适的能量源时能够被去除的保护基团。 表面上预定区域的空间照射辐射允许在表面上的活化区域上固定抗配体。 表面不同区域的照射周期和不同抗配体的固定允许在表面上限定的位点形成固定的抗配体基团。 抗配体的固定化基质允许对基质的某些抗配体具有高亲和力的配体的液体样品的同时筛选。 本发明的优选实施方案涉及将可光活化的生物素衍生物连接到表面。 生物素衍生物的光解活化形成对抗生物素蛋白具有强结合亲和力的生物素类似物。 生物素化的抗配体可以固定在先前用抗生物素蛋白处理的表面的活化区上。
