The 'total protein staining' of biological specimens with the electrostatically binding Naphthol Yellow S or the covalently binding dinitrofluorobenzene must be interpreted as methods which yield data on the specific amino acid pool of the proteins concerned. Both dyes bind to certain free amino-acid side-chains, giving different dye--protein ratios for various proteins. In the presence of DNA, dinitrofluorobenzene stains all proteins present in cell nuclei, whereas Naphthol Yellow S only stains the majority of the non-histone proteins. When protein staining methods are combined with the Feulgen--Pararosanile (SO2) procedure for DNA, decreased Feulgen--DNA contents were measured in dinitrofluorobenzene-stained isolated nuclei and lymphocytes.
用静电结合的萘酚黄S或共价结合的二硝基氟苯对生物标本进行“总蛋白染色”,必须理解为这些方法可提供有关相关蛋白质特定氨基酸库的数据。两种染料都与某些游离氨基酸侧链结合,不同蛋白质的染料 - 蛋白质比例不同。在DNA存在的情况下,二硝基氟苯可对细胞核中存在的所有蛋白质进行染色,而萘酚黄S仅对大多数非组蛋白进行染色。当蛋白质染色方法与用于DNA的福尔根 - 副蔷薇苯胺(SO2)程序结合使用时,在二硝基氟苯染色的分离细胞核和淋巴细胞中测量到福尔根 - DNA含量降低。
