The primary antibody desorbs from its corresponding antigen and transfers through an intermediate onto the second (double-blot) membrane. When the double-blot membrane is probed with the secondary antibody, no other proteins are present to bind nonspecifically, thus eliminating the background problem...
一抗稀释液(Western Blot) 英文名称: Western Blot Primary Antibody Dilution Buffer 一抗稀释液(Western Blot)产品规格: 100ml 发货周期: 1~3天 一抗稀释液(Western Blot) 可以用于Western 时一抗(Primary Antibody)的稀释和配制。使用本抗体稀释液稀释和配制的一抗可以在4℃保存和使用不少于6 个月,可以反复多...
Remove the blocking buffer and add enough diluted primary antibody to cover the membrane. Incubate the membrane with primary antibody for 1hr at R/T. (Note: Or you can do overnight incubation at 4C, make sure you cover the western-blot tray to prevent excessive evaporation). To prevent une...
Western Blot实验成功必备利器---内参抗体 · 什么是内参? 内参是一种特异识别高表达或普遍表达蛋白的抗体,在western blot中用于校正蛋白水平。 · 选择内参时需要考虑什么? 1. 检测大小:选择和目的蛋白大小相近的内参,但仍要能与目的蛋白区分开,足够大于或小于目的蛋白。若目的蛋白和内参的分子量大小相同,则不利于...
Western Blot采用的是聚丙烯酰胺凝胶电泳,被检测物是蛋白质,“探针”是抗体,“显色”用标记的二抗。经过PAGE分离的蛋白质样品,转移到固相载体(例如硝酸纤维素薄膜)上,固相载体以非共价键形式吸附蛋白质,且能保持电泳分离的多肽类型及其生物学活性不变。以固相载体上的蛋白质或多肽作为抗原,与对应的抗体起免疫反应,再...
二抗结合以及后续的化学发光检测等一系列步骤后,可能需要对相同样品中其他蛋白(不同一抗结合)进行检测,或者在相同蛋白(相同一抗)的第一次检测结果不佳从而需要优化检测体系的情况,为了节省工作时间,节省样本使用量,以及消除重新上样可能引起的误差,可通过使用蛋白印迹膜再生液(Western Blot Antibody Stripping Solution)...
Thewestern blot(also known as immunoblotting, because an antibody is used to identify its antigen) is a widely used analytical method often used by researchers to detect the presence of a protein in a given sample (Towbin, Staehelin, & Gordon, 1979) (Fig. 23.2). Thewestern blotcan also ...
5. Antibody staining 1. Block the membrane for 1-2 hours at room temperature using 5% blocking solution. 2. Incubate membrane with appropriate dilutions of primary antibody (Appendix 2) in antibody dilution buffer overnight at 4°C. 3. Wash the membrane in three washes of 1xTBST, 5 ...
