The present invention relates to a microarray comprising at least 50,000 oligopeptide features per cm2 where the oligopeptide features represent at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 99%, or 100% of the proteome of a virus or an organism. The present invention further relates to methods for the synthesis of such microarrays and methods of using microarrays comprising at least 50,000 oligopeptide features per cm2. In an embodiment of the invention, the oligopeptide features represent proteins expressed in the same species, wherein the oligopeptide features are presented in a tiling pattern representing at least about 5,000, at least about 10,000, at least about 15,000, at least about 20,000, or at least about 25,000 proteins expressed in a species. In some embodiments, the oligopeptide microarray features represent proteins expressed in the same species, wherein the microarray features are present in a tiling pattern that represents between about 5,000 and 50,000 expressed proteins, between about 10,000 and 50,000 expressed proteins, between about 15,000 and 50,000 expressed proteins, between about 20,000 and 50,000 expressed proteins, or between about 25,000 and 50,000 expressed proteins.
本发明涉及一种包括每平方厘米至少 50,000 个寡肽特征的微阵列,其中寡肽特征代表病毒或生物体蛋白质组的至少 50%、至少 60%、至少 70%、至少 80%、至少 90%、至少 95%、至少 99%或 100%。本发明进一步涉及合成这种微阵列的方法和使用每平方厘米至少包含 50,000 个寡肽特征的微阵列的方法。在本发明的一个实施方案中,寡肽特征代表在同一物种中表达的蛋白质,其中寡肽特征以平铺模式呈现,代表在一个物种中表达的至少约 5,000 个、至少约 10,000 个、至少约 15,000 个、至少约 20,000 个或至少约 25,000 个蛋白质。在某些实施方案中,寡肽微阵列特征代表在同一物种中表达的蛋白质,其中微阵列特征以平铺模式呈现,代表约 5,000 至 50,000 个表达的蛋白质、约 10,000 至 50,000 个表达的蛋白质、约 15,000 至 50,000 个表达的蛋白质、约 20,000 至 50,000 个表达的蛋白质或约 25,000 至 50,000 个表达的蛋白质。
