产品详细介绍

简要概述

链霉亲和素缀合物广泛用于和生物素缀合物结合以检测多种生物靶标,例如蛋白质,核酸和其他分子。它们被用作许多生物检测的理想选择,例如免疫荧光显微镜,流式细胞术,蛋白质印迹和其他生物应用,因为链霉亲和素具有很强的亲和力结合生物素,在广泛的pH和温度范围内都不会受到影响。AAT Bioquest®提供多种标记有经典荧光染料的链霉亲和素偶联物(例如:FITC,TRITC,TexasRed®,Cy3®,Cy5®和Cy7®),以及我们优异的水溶性,光稳定性iFluor 和mFluor 染料。然而,常规的生物素-亲和素检测系统仍然受到现有荧光缀合物有限信号强度的限制。链霉亲和素Xtra iFluor缀合物是超亮链霉亲和素缀合物的新家族,其激发和发射性能与Alexa Fluor荧光团几乎相同,信号增强了3到5倍。它是在细胞成像或流式细胞仪中检测低丰度靶标的一组强大工具。iFluor 488是FITC通道成像中最常见的绿色荧光色之一。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的链霉亲和素-Xtra IF488缀合物。

样品实验方案 

溶液配制

1.储备溶液配制

所有未使用的储备溶液应分为一次性使用的等分试样,并在制备后储存在-20°C下。 避免重复冻融循环。
链霉亲和素-Xtra 储备溶液(1 mg / mL):加入100 uL的Cat#46000和1 mL的Cat#46001的ddH2O,制成1mg/mL的储备溶液。注意:此重组溶液在4°C储存并避光保存后,可稳定保存6个月而无明显变化。为了更长的存储时间,可以将重构的溶液分成单次使用的等分试样,或者不分装添加等体积的甘油(最终浓度为50%),然后将溶液存储在-20°C(避光)。

 

2.工作溶液配制

链霉亲和素-Xtra 工作溶液:对于IF,建议的染色浓度为1-5 ug / ml。对于FACS,建议在染色浓度为0.1-0.5 ug / 100 uL /百万细胞。注意: PBS + 0.1%BSA可用作染色缓冲液。 注意:为了获得每种应用的最佳性能,需要仔细确定该试剂的最佳浓度。注意:  建议的工作稀释度仅供参考,建议用户在测试中使用适当的阳性和阴性对照对产品进行滴定。

样品示例及操作

  1. 按照说明书中的建议用目标抗体封闭和处理样品。
  2. 在样品中以适当的浓度和持续时间添加生物素偶联的二抗工作溶液。注意:请验证您的生物素偶联抗体与实验中使用的一抗的相容性和类型。例如,如果一抗是小鼠抗体,则与生物素结合的山羊抗小鼠抗体可用于该测定。
  3. 在室温下用链霉亲和素-Xtra 工作溶液孵育细胞30分钟至1小时。 注意:  孵育的最佳时间需要仔细确定。
  4. 取出工作溶液,然后将细胞重悬在缓冲液中。
  5. 使用荧光显微镜拍摄图像或使用流式细胞仪记录强度。

产品介绍
 

羊抗鼠二抗是亲和纯化的抗体,对小鼠免疫球蛋白具有很好的特异性,可用于检测,分离或纯化其特定靶标。二抗提供了更多的多功能性,使用户可以使用许多检测系统(例如HRP,AP,荧光)。它们还可以通过信号放大来提供更高的灵敏度,因为多个二级抗体可以与单个一级抗体结合。MegaWox polyHRP-羊抗鼠IgG缀合物设计用于在样品量有限或目标分子含量低的免疫分析中提供最高的灵敏度和较低的背景。纯化羊抗鼠IgG聚-HRP缀合物以除去未缀合的羊抗鼠IgG分子,该分子与其HRP缀合物竞争结合位点。另外,缀合物没有可引起背景信号的未缀合的HRP。MegaWox polyHRP-山羊抗小鼠IgG与用于ELISA,Western印迹,免疫组织化学(IHC)和核酸杂交测定的荧光和化学发光HRP底物兼容。我们的TSA和Styramide 荧光HRP底物可以一起用于超灵敏检测低丰度生物靶标。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的MegaWox polyHRP-羊抗鼠IgG缀合物。
