dot－blot的詳細步驟
蛋白質印跡法（免疫印跡試驗）即Western Blot。它是分子生物學、生物化學和免疫遺傳學中常用的一種實驗方法。其基本原理是通過特異性抗體對凝膠電泳處理過的細胞或生物組織樣品進行著色。通過分析著色的位置和著色深度獲得特定蛋白質在所分析的細胞或組織中表達情況的信息。

斑點雜交（Dot－blot）法
斑點雜交（Dot blot）是將被檢標本點到膜上，烘烤固定。這種方法耗時短，可做半定量分析。一張膜上可同時檢測多個樣品，為使點樣準確方便，市售有多種多管吸印儀（Manifold），如MinifoldⅠ和Ⅱ、Bio-Dot（Bio-Rad）和Hybri-Dot,它們有許多孔，樣品加到孔中，在負壓下
一種基于DNA的通用型蛋白檢測系統
摘要：基于抗體的蛋白質檢測方法，主要有western blot、ELISA、點雜交以及免疫組化等，這些方法被廣泛地應用于科研和診斷領域。在蛋白質的免疫檢測過程中，樣品蛋白首先結合與特異性一抗上，然后再用攜帶標簽（諸如：熒光染料，放射性元素，酶等）的二抗進行檢測。然而，為了避免種間內的交叉反應，必
