DNAseposttreatmentfornuclearantigens
Rationale: The use of DNAse to improve nuclear antigen staining has been published long before the AR era 1, 2.DNAse treatment is currently suggested as an unmasking technique for incorporated BrdU nucleotides 3.However, BrdU detection in dewaxed, fixed tissues with DNAse treatment leads to poorly reproducible results. BrdU instead is readily demonstrated after conventional AR treatment (EDTA 0.01M, pH......閱讀全文

NMR（Nuclear－Magnetic－Resonance）為核磁共振的應用介紹
核磁共振適合于液體、固體。如今的高分辨技術,還將核磁用于了半固體及微量樣品的研究。核磁譜圖已經從過去的一維譜圖(1D)發展到如今的二維(2D)、三維(3D)甚至四維(4D)譜圖,陳舊的實驗方法被放棄,新的實驗方法迅速發展,它們將分子結構和分子間的關系表現得更加清晰。在世界的許多大學、研究機構和企業集
在分離正常人尿DNase時的凝膠電泳
觀察用葡聚糖凝膠分離人尿中DNase時可以除去大部分其他蛋白質和雜質。但分離所得的制品用凝膠電泳觀察還可以見到五條以上的蛋白質區帶。將凝膠條在未染色前置于含大分子DNA的瓊脂平板上，在37℃溫箱中保溫2-3小時，再用5%三氯醋酸加至如此處理過的瓊脂板上，可以看到乳白色本底上出現被酶水解后的透明斑點。
