General description
双缩脲和 Lowry 程序用于蛋白质测定。前者广泛用于临床检测。后者尽管更灵敏,却只用于研究工作,受限于组合试剂的低稳定性、颜色的不可再现性(特别是在低蛋白浓度下)以及和蛋白质浓度的非线性显色反应。Ohnishi 和 Barr 改良了用于 Lowry 测定法的双缩脲试剂,从而简化了流程,同时提高了组合试剂的稳定性。
Application
全蛋白试剂盒( Micro-Lowry, Onishi & Barr Modification )已用于测定以下物质的总可溶蛋白质浓度:
- 麦醇溶蛋白的透析液/提取物
- 面粉(燕麦 和 硬粒小麦)和种子(藜麦, 芡欧鼠尾草)的提取物
- 储存的大鼠肝微粒体部分样品
Biochem/physiol Actions
比色法,终点。 化验。Ohnishi 和 Barr′s 对微 Lowry 方法的改进。根据实验步骤,稀释的缩二脲试剂与肽键反应生成紫蓝色复合物,通过加入苯酚试剂增强其颜色。在 550-750 nm 处读取的吸光度用于确定标准曲线的结果。
试剂盒组分也可单独购买

Manipulation of circulating histidine-containing dipeptides (HCD) has been shown to affect the development of diabetes and early-stage diabetic nephropathy (DN). The aim of the present study was to investigate whether such interventions, which potentially alter levels of circulating HCD, also

We isolated goat phosphopeptides via calcium and ethanol precipitation from a caseinate digest and investigated their feasibility as an iron-fortification ingredient in nutritional foods. Goat tryptic-digested phosphopeptides could bind 54.37 ± 0.50 mg of Fe/g of protein compared with goat
