The kit includes Alizarin Red Solution, a staining solution which can be used to visually detect the presence of mineralization in bone tissue. Also included are reagents for extraction of Alizarin Red from stained cells, and a protocol for performing quantitative analysis of the extracted Alizarin Red. Enough reagents are provided to perform 48 quantitation assays on 24 well plates.
For Research Use Only. Not for use in diagnostic procedures.
One vial containing 5 mL of ARS (Alizarin Red Stain) Diluent is provided. Add 5 mL of 80% Acetic Acid for a final volume of 10 mL before use.

法是十分常用的蛋白质比色定量方法,很多试剂供应商都提供基于比色皿和微孔板的BCA蛋白定量试剂盒。BCA蛋白定量法相对于其它比色定量法具有操作简单、稳定、灵敏度高等优点。相对于蛋白质的固有的280nm吸收峰检测,BCA检测法提高了蛋白检测灵敏度和特异性,消除了核酸的干扰,核酸干扰在对细胞裂解物或其他生物样品进行蛋白定量时总是一个难以避免的干扰。在碱性条件下,蛋白将Cu2+ 还原为Cu+ ,Cu+ 与BCA 试剂形成紫色络合物,如图1,其吸光值与蛋白浓度成正比。测定在562nm 处的吸收值,并与标准
%匀浆(例如10mg加入100ulRIPA裂解液),进行匀浆。冰上孵育20min后,13000rpm(4度)离心20min。取上清,分装-80度保存,待测。 2. BCA法蛋白定量 按照BCA蛋白定量试剂盒使用说明操作,测定蛋白浓度。 1、根据样品数量,试剂A:B=50:1配制适量BCA工作液,充分混匀。BCA工作液室温24小时内稳定。 2、完全溶解蛋白标准品,取10μl稀释至100μl,使终浓度为0.5mg/ml。 3、将标准品按0, 1, 2, 4, 8, 12, 16, 20μl加
