dot－blot的详细步骤
蛋白质印迹法（免疫印迹试验）即Western Blot。它是分子生物学、生物化学和免疫遗传学中常用的一种实验方法。其基本原理是通过特异性抗体对凝胶电泳处理过的细胞或生物组织样品进行着色。通过分析着色的位置和着色深度获得特定蛋白质在所分析的细胞或组织中表达情况的信息。

斑点杂交（Dot－blot）法
斑点杂交（Dot blot）是将被检标本点到膜上，烘烤固定。这种方法耗时短，可做半定量分析。一张膜上可同时检测多个样品，为使点样准确方便，市售有多种多管吸印仪（Manifold），如MinifoldⅠ和Ⅱ、Bio-Dot（Bio-Rad）和Hybri-Dot,它们有许多孔，样品加到孔中，在负压下
