ImmunoReagents正常血清简介

ImmunoReagents正常血清简介

正常非免疫血清在免疫分析中有多种用途。它含有一整套内源性血清蛋白,包括在正常健康动物中发现的所有类别的免疫球蛋白。血清可以在许多免疫分析中用作阳性或阴性对照,或者在ELISA、IHC和Western印迹中常用作阻断剂。5%(v/v)的血清溶液足以饱和并阻断固定组织或分析基质上的非特异性部位。

注意事项 This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications.
产品介绍 Goat Serum blocking reagent or NGS can be used as a blocking agent to treat plastic surfaces, membrane or tissue after they have been sensitized with primary antibody or antigen. It provides an alternative to bovine serum albumin (BSA) and non-fat dry milk. It is effective in reducing nonspecific binding of proteins to reaction surfaces, thereby maximizing signal-to-noise ratio. This blocking agent is recommended for use in immunoassays where the primary antibody was produced in goat, as a source of non-specific serum protein or on tissue for immunohistochemical applications.
Application: Goat Serum blocking reagent or NGS is ideal for blocking procedures such as Western Blotting, ELISA and immunochemistry to prevent nonspecific binding.

封闭血清适用于免疫组化或者免疫荧光实验中样本的封闭。可以封闭待检样本中与蛋白质非特异性结合的位点,另外还可以封闭样品中内源性的 Fc 片段结合位点,阻断抗体与样品中的 Fc 受体结合,从而降低背景,减少假阳性。在选择封闭血清时,要注意封闭用血清中不能含有目标蛋白,且与一抗来源不同,可用与二抗相同来源的封闭血清。正常山羊血清被广泛应用于组织和细胞染色中非特异性抗体结合的阻断,以及抗体的其他应用。血清可直接用于阻断,或作为阻断缓冲液的成分。

使用方法:

免疫组化:用5-10%正常山羊血清封闭(1:10-1:20倍稀释),室温孵育5-10分钟。清除血清,勿洗,滴加适当比例稀释的一抗或一抗工作液,37℃或室温孵育4℃过夜。

细胞涂片:用5-10%正常山羊血清封闭(1:10-1:20倍稀释),使用 PBS 稀释( 0.01mol/L pH7.4),少量点滴:漠过细胞涂片即可.

ELISA:1:100倍稀释 使用 PBS 稀释( 0.01mol/L pH7.4)37℃一小时。

《科学》:如何让癌症干细胞正常

来自加拿大麦克马斯特大学等处的研究人员发表文章,发现一种药物:硫利达嗪(Thioridazine)能成功消灭人体癌症干细胞,从而避免了传统癌症治疗方法引起的毒副作用。这一重要的成果公布在5月24日的Cell杂志上。

领导这一研究的是加拿大麦克马斯特大学干细胞与癌症研究院科学主任Mick Bhatia教授,他表示,“这项研究发现不同寻常之处在于,这种已有药物实际杀死癌症干细胞的方式——将这些癌症干细胞变成正常非癌变细胞”。Bhatia教授一直致力于癌症干细胞的研究,他曾*次论证了人类正常干细胞和癌症干细胞的区别。

15年以来,科学家们都认为干细胞是许多癌症的源头。1997年加拿大的科学家*次在某种白血病中识别出了癌症干细胞,自此癌症干细胞便陆续在血癌,乳腺癌,脑癌,肺癌,胃肠道癌症,前列腺癌以及卵巢癌中被发现。

与正常干细胞不同,癌症干细胞不会分化成稳定的,非分裂细胞类型,之前Bhatia教授曾利用一种筛选平台,按照其表达的基因和起反应的药物来定义这两者之间的差别,从而能够开发能更好地对付癌细胞而不损害健康细胞的疗法和药物。

而这项研究中,Bhatia教授和他的同事通过药物研发模型,筛选了上百种化合物,从中鉴别出来将近20种潜在的癌症干细胞特异性药物,其中一种可能zui有潜力的药物就是这种称为硫利达嗪的化合物。

硫利达嗪(Thioridazine)实际上是一种治疗精神疾病的药物,可以通过靶向大脑中的多巴胺受体,来治疗精神躯体障碍所致焦虑和紧张状态。这种药物其实并不能杀死癌症干细胞,但是却能促进癌症干细胞分化,从而消耗干细胞的自我更新能力。

研 究人员发现,硫利达嗪能由此消灭白血病干细胞,并且不会影响正常血液干细胞,将白血病患者体内的癌症干细胞蛋白与正常血细胞中的蛋白进行比较,能帮助解释 这种特异性。血癌细胞与正常血液干细胞不同,前者表面能表达一种多巴胺受体,而多巴胺受体也能在某些乳腺癌细胞中表达。

“这进行了一些解释”,Bhatia教授说,而且这也说明多巴胺受体也许能作为一种罕见肿瘤驱动细胞的生物标记物。

利用这些发现,Bhatia教授研究组目前正计划进行硫利达嗪这种FDA批准药物的临床实验,结合标准的成人急性髓细胞白血病抗癌药物,以及这种药物进行治疗。

“我们很高兴看到能将这种药物引入临床”,Bhatia教授说,“我们也希望这一平台能成为其它癌症干细胞药物筛选的流水线。”
