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......阅读全文

NMR（Nuclear－Magnetic－Resonance）为核磁共振的应用介绍
核磁共振适合于液体、固体。如今的高分辨技术,还将核磁用于了半固体及微量样品的研究。核磁谱图已经从过去的一维谱图(1D)发展到如今的二维(2D)、三维(3D)甚至四维(4D)谱图,陈旧的实验方法被放弃,新的实验方法迅速发展,它们将分子结构和分子间的关系表现得更加清晰。在世界的许多大学、研究机构和企业集
在分离正常人尿DNase时的凝胶电泳
观察用葡聚糖凝胶分离人尿中DNase时可以除去大部分其他蛋白质和杂质。但分离所得的制品用凝胶电泳观察还可以见到五条以上的蛋白质区带。将凝胶条在未染色前置于含大分子DNA的琼脂平板上，在37℃温箱中保温2-3小时，再用5%三氯醋酸加至如此处理过的琼脂板上，可以看到乳白色本底上出现被酶水解后的透明斑点。
