The invention describe protein arrays and their use to assay, in a parallel fashion, the protein products of highly homologous or related DNA coding sequences. By highly homologous or related it is meant those DNA coding sequences which share a common sequence and which differ only by one or more naturally occurring mutations such as single nucleotide polymorphisms, deletions or insertions, or those sequences which are considered to be haplotypes (a haplotype being a combination of variations or mutations on a chromosome, usually within the context of a particular gene). Such highly homologous or related DNA coding sequences are generally naturally occurring variants of the same gene. Arrays according to the invention have multiple for example, two or more, individual proteins deposited in a spatially defined pattern on a surface in a form whereby the properties, for example the activity or function of the proteins can be investigated or assayed in parallel by interrogation of the array.
本发明描述了蛋白质阵列及其在平行检测高度同源或相关 DNA 编码序列的蛋白质产物方面的用途。所谓高度同源或相关,是指那些具有共同序列的 DNA 编码序列,它们之间仅有一个或多个自然发生的突变,如单核苷酸多态性、缺失或插入,或那些被认为是单倍型的序列(单倍型是染色体上变异或突变的组合,通常在特定
基因的范围内)。这种高度同源或相关的 DNA 编码序列通常是同一
基因的天然变体。根据本发明,阵列具有多个,例如两个或更多的单个蛋白质,以空间定义的模式沉积在表面上,通过对阵列的询问,可以平行地研究或测定蛋白质的特性,例如活性或功能。
