产品介绍
产品介绍 : 阿拉丁生产的脱脂奶粉(Blotting Grade),即nonfat powdered milk, non-fat powdered milk, nonfat dry milk or skim milk for western blotting applications,是通过将精选的低免疫源性的鲜牛奶脱去脂肪后干燥而成,并经Western检测验证可以用于配制Western检测时的封闭液(Blocking Buffer)、一抗稀释液和二抗稀释液。脱脂奶粉是最常用的Western检测的封闭液组分之一。本产品溶解性好,使用本产品封闭后,可以有效减少一抗或二抗和膜的非特异性结合,降低背景,增强信噪比。脱脂奶粉配制的封闭液和BSA(牛血清白蛋白)配制的封闭液不同,前者是不透明的,后者是透明的。更多的用户喜欢使用BSA作为主要的有效封闭成分。但BSA的价格远高于脱脂奶粉。对于特定目标蛋白的Western检测,有时使用BSA作为主要封闭组分的效果更好,有时使用脱脂奶粉的封闭效果更好。通常优先参考一抗生产商推荐的封闭液进行封闭,如果封闭效果不好,可以尝试BSA和脱脂奶粉中的另外一种。如果希望快速有效地完成封闭和检测,推荐使用阿拉丁生产的UltraBio™系列产品,包括UltraBio™Western封闭液、UltraBio™ Western一抗稀释液和UltraBio™ Western二抗稀释液等多个产品。UltraBio™系列产品能实现超快速并且更好效果的的封闭。 注意事项 : 通常在室温封闭60分钟即可。如果对于一些背景非常高的抗体,可以尝试4℃封闭过夜。脱脂奶粉成分比较复杂,可能含有微量的生物素,故不适合生物素-亲和素检测系统。尽量避免用于稀释anti-goat及anti-sheep的二抗。本产品仅限于专业人员的科学研究用,不得用于临床诊断或治疗,不得用于食品或药品,不得存放于普通住宅内。为了您的安全和健康,请穿实验服并戴一次性手套操作。 使用说明 : 1.配制Western封闭液:脱脂奶粉的浓度通常为3-5%(w/v),推荐使用阿拉丁生产的P0023C Western洗涤液或者稀释成1X的P0023C3 Western洗涤液(10X)或P0023C6 Western洗涤液(10X)进行配制,也可以使用TBSTw (20 mM Tris pH 7.6, 137 mM NaCl, 0.1% Tween 20)进行配制。2.一抗和二抗也可以用该封闭液稀释。3.样品完成转膜后,用Western洗涤液洗涤蛋白膜1-2分钟。加入Western封闭液,封闭60分钟后,然用Western洗涤液洗涤蛋白膜1-2次,每次1-2分钟。随后进行一抗孵育等后续操作。详细的Western操作可以参考如下的相关网页:https://www.aladdin-e.com
