一、蛋白質組學概論隨著人類基因組計劃的實施，生命科學步入了后基因組時代，出現了不同于以往經典生物實驗科學的全新的研究方式─“生物大科學”。這種生物大科學的核心思想是整體性研究，即以生物體內某類物質為對象進行完整的研究。過去對生命活動的研究僅限于研究細胞內個別的基因或蛋白質，而基因組學和蛋白質組學的目

我們本次實驗使用的是銀染。銀染的方法種類很多，目前有文獻報道的就有100多種。但是其準確的染色機制還不是特別的清楚。大致的原理是銀離子在堿性pH環境下被還原成金屬銀，沉淀在蛋白質的表面上而顯色。 由于銀染的靈敏度很高，可染出膠上低于1 ng/蛋白質點，故廣泛的用在2D凝膠分析上。待找到自己感
血紅蛋白電泳（hemoglobin－electrophoresis）（HbA2定量）
實驗原理血紅蛋白電泳（hemoglobin electrophoresis）目的是檢出和確認各種正常和異常的血紅蛋白。根據不同的血紅蛋白帶有不同的電荷，等電點不同，在一定的pH緩沖液中，血紅蛋白的等電點小于緩沖液的pH時帶負電荷，電泳時在電場中向陽極泳動，反之，Hb帶正電荷向陰極泳動。在一定電壓下，

六、第二向 SDS-PAGE1．[基本原理]蛋白質在聚丙烯酰胺凝膠中電泳時，它的遷移率取決于它所帶凈電荷以及分子的大小和形狀等因素。如果加入一種試劑消除電荷、形狀等因素的影響，使電泳遷移率只取決于分子的大小，就可以用電泳技術測定蛋白質的分子量。1967年，Shapiro等發現在樣品介質和聚丙烯酰胺凝
