Methods for producing ligand arrays, e.g., peptide and nucleic acid arrays, as well as the arrays produced thereby, methods for use of the arrays and kits that include the same are provided. In one embodiment of the subject methods, a substrate having a surface displaying acetate functional groups that produce surface bound hydroxyl functional groups upon hydrolysis is first provided, where the acetate groups are then hydrolyzed to hydroxyl functional groups. In another embodiment of the subject methods, a substrate having a surface displaying alkenyl functional groups is first provided, where the alkenyl functional groups are then converted to carboxylic functional groups. The resultant substrates, optionally after an additional functionalization step, are then contacted with ligands, e.g., via deposition of each different ligand onto a different region of the surface, resulting in covalent attachment of the contacted ligands to the surface. The subject methods find use in the preparation of a variety of different types of arrays, where the produced arrays find use in a variety of different applications, including both genomic and proteomic applications.
本发明提供了生产配体阵列(如肽和核酸阵列)的方法,以及由此生产的阵列、阵列的使用方法和包括相同内容的试剂盒。在该主题方法的一个实施方案中,首先提供一种表面显示醋酸官能团的基底,该醋酸官能团在水解时产生表面结合的羟基官能团,然后醋酸官能团被水解为羟基官能团。在本主题方法的另一个实施方案中,首先提供一种表面显示烯基官能团的基质,然后将烯基官能团转化为羧基官能团。在经过额外的官能化步骤后,可选择将得到的基底与配体接触,例如通过将每种不同的配体沉积到表面的不同区域,从而使接触的配体与表面共价连接。上述方法可用于制备各种不同类型的阵列,制备的阵列可用于各种不同的应用,包括基因组和蛋白质组应用。
