The present disclosure relates to polymer coatings covalently attached to the surface of a substrate and the preparation of the polymer coatings, such as poly(N-(5-azidoacetamidylpentyl)acrylamide-co-acrylamide) (PAZAM), in the formation and manipulation of substrates, such as molecular arrays and flow cells. The present disclosure also relates to methods of preparing a substrate surface by using beads coated with a covalently attached polymer, such as PAZAM, and the method of determining a nucleotide sequence of a polynucleotide attached to a substrate surface described herein.
本公开涉及共价连接到基底表面的聚合物涂层和聚合物涂层的制备,例如聚(N-(5-
叠氮乙酰胺戊基)
丙烯酰胺-共
丙烯酰胺)(PAZ
AM),用于形成和操作基底,例如分子阵列和流动池。本公开还涉及通过使用涂有共价连接聚合物(如 PAZ
AM)的珠子制备基底表面的方法,以及确定附着在本文所述基底表面的多核苷酸的核苷酸序列的方法。
