产品介绍

阿拉丁生产的UltraBio™免疫染色二抗稀释液(UltraBio™SecondaryAntibodyDilution BufferforImmunostaining)是一种通过直接用于二抗的稀释,增强免疫染色(包括免疫荧光、免疫组化等)检测时二抗的特异性结合,从而可以使免疫染色检测的灵敏度增强数倍至十几倍的增敏试剂。本产品通过大规模精细筛选获得很可能通过粘附、缠绕或捆绑特异性结合的抗原抗体复合物的大分子化合物,以及配套的降低背景的封闭试剂和去垢剂组合,从而有效解决免疫染色检测过程中经常遇到的低灵敏度和高背景等问题,极大地提高了信噪比。本产品可用于免疫荧光(Immunofluorescence)、免疫组化(Immunohistochemistry)、免疫斑点印迹(DotBlot)和ELISA等其它涉及抗原抗体结合的免疫检测的增敏,也可以尝试用于其他蛋白相互作用检测的增敏。免疫染色,即Immunostaining,包括免疫荧光(Immunofluorescence)、免疫组化(Immunohistochemistry)、免疫细胞化学(Immunocytochemistry)等,是用抗体检测蛋白表达的主要方法之一。通常的步骤包括固定、抗原修复、封闭、一抗孵育、二抗孵育和二抗标记物检测等步骤,可参考阿拉丁的网页详细介绍:http://www.aladdin-e.com/。免疫染色实验过程中,会遇到如下的常见问题:目的蛋白丰度低或抗体效价低而导致目的蛋白染色信号弱;封闭效果不好而导致背景高;抗体特异性不好而导致非特异性条带强等问题。解决此类问题通常需要经过长时间的条件优化,特别是更换抗体或增加抗体用量会增加实验成本。本产品可极大提高目的蛋白的信号强度:本产品通过促进抗原抗体的特异性结合,产生的信号强度会比传统方法高数倍甚至十几倍,可以提高低丰度蛋白的检测成功率或节省抗体的用量。本产品使获得的检测结果更佳:本产品可有效降低背景,并且使目的蛋白信号更强,容易获得更理想的免疫染色检测结果。本产品可提高抗体特异性:本产品中包含了高效的封闭试剂和降低非特异性结合的去垢剂组合,可以有效提高抗体的特异性,降低非特异性条带的信号,获得更好的免疫染色检测结果。本产品可节省抗体使用量:与传统的方法相比,本产品的检测信号会增强很多,可以适当减少二抗的用量,有效节约实验成本。同时,本产品稀释和配制的二抗可以在4℃保存,后续可以反复多次用于免疫染色,利于节约二抗。本产品使用便捷:本产品是一种即用型溶液,直接用于二抗的稀释配制即可,不增加任何额外的实验步骤,不改变常规的免疫染色检测步骤。对于较难检测的目的蛋白,可以节省用于目的蛋白检测优化的时间和精力。本产品的样品兼容性好:可以用于培养的贴壁细胞或悬浮细胞,也可以用于冰冻切片或石蜡切片。本产品的检测底物兼容性好:本产品的组分对各种标记二抗的检测均没有影响,兼容辣根过氧化物酶(Horseradish peroxidase, HRP)、碱性磷酸酶、生物素或地高辛标记的二抗,对于荧光检测和显色检测都可以适用。本产品应用范围广:本产品特别适用于免疫荧光、免疫组化和免疫细胞化学,也适用于免疫斑点印迹和ELISA等其它涉及抗原抗体相互作用的免疫检测。本产品可以用于二抗的稀释,也可以用于一抗的稀释。4℃保存,一年有效。长期不使用可以


使用说明

1. 参考所用抗体的说明,以及样品中目的蛋白的含量,使用本产品按照适当比例稀释二抗。抗体稀释后即可直接用于免疫染色检测,免疫染色检测的方法步骤不变。免疫染色检测结束后,可以回收稀释的抗体,4℃保存,以用于下次的免疫染色检测。2. 详细的免疫染色操作可以参考如下的相关网页:http://www.aladdin-e.com/support/immunol-staining.htm。

To ensure the best results, we recommend using this product in conjunction with QuickBlock™ Blocking Buffer for Immunol Staining or Immunol Staining Blocking Solution , and Immunol Staining Wash Buffer .A small amount of white precipitates may occur in this product after stored at low temperatures or frozen at -20°C. Before use, the precipitates should be completely dissolved by incubating the bottle in a 30-50°C water bath for an appropriate period of time.Secondary antibodies diluted and prepared with this product can be stored at 4ºC for multiple uses in immunostaining, but should be discarded when there is turbidity, precipitation, or a decrease of assay efficacy.Diluted antibodies should be stored at 4℃ immediately after use to enable multiple uses.This product is recommended for secondary antibody dilution, but not for sample blocking.For secondary antibody dilution, there is no need to add other blocking reagents such as BSA, skim milk powder, and casein, as this product has been optimized to have good blocking effect. The addition of other blocking reagents may have some negative effects.The effect of this product varies for different target proteins and antibodies.If the signal of the target protein is very strong, non-specific signals will be enhanced accordingly. If the non-specific signal intensity is very close to that of target protein, attempt to decrease the concentration of antibody or shorten the exposure time appropriately.This product is for R&D only. Not for drug, household, or other uses.For your safety and health, please wear a lab coat and disposable gloves during the operation.


Instructions for Use

1. Dilute the secondary antibody with this product at an appropriate ratio according to manufacture's instructions of the antibody used and the content of target protein in samples. The diluted secondary antibody can be recovered and stored at 4ºC for later use in immunostaining.
