IRDye 680RD Streptavidin can be used as a secondary detection reagent for protein arrays, microscopy, In-Gel Westerns, a
IRDye 680RD Streptavidin is supplied as a liquid in buffer containing 10 mM phosphate, 183 mM NaCl, 2.7 nM KCl, pH 7.4 with sodium azide 0.005% (w/v) as a preservative.
To use, centrifuge briefly before use to eliminate aggregates that may have formed in solution. This will reduce non-specific background staining. A final concentration of 0.2 to 1.0 µg/ml (1:1,000 to 1:5,000) is usually satisfactory for most applications; however, appropriate dilution may need to be determined empirically.
For membrane-based applications and In-Gel Westerns, it is recommended to add SDS (0.02% to 0.1% final concentration), in addition to Tween® 20 (0.1 to 0.2% final concentration) during the detection incubation step to reduce non-specific background staining.
Recommended Dilutions
Application | Suggested Range | Tween 20* | SDS* |
---|---|---|---|
Odyssey® Western blot detection | 1:1,000 - 1:5,000 | 0.1 - 0.2% (v/v) | 0.02 - 0.1% (v/v) |
Other | User optimized | User optimized | User optimized |
Optimum dilutions will vary and should be determined empirically.
* Added to reduce non-specific background staining.

请问有什么方法检测细胞内活性氧更好,各位有什么经验,及相关试剂盒推荐一下。
(1)优级纯试剂 亦称保证试剂,为一级品,纯度高,杂质极少,主要用于精密分析和科学研究,常以GR表示。
(2)分析纯试剂 亦称分析试剂,为二级品,纯度略低于优级纯,杂质含量略高于优级纯,适用于重要分析和一般性研究工作,常以AR表示。
(3)化学纯试剂 为三级品,纯度较分析纯差,但高于实验试剂,适用于工厂、学校一般性的分析工作,常以CP表示。
(4)实验试剂 为四级品,纯度比化学纯差,但比工业品纯度高,主要用于一般化学实验,不能用于分析工作,常以 LR表示。
以上按试剂纯度的分类法已在我国通用。根据化学工业部颁布的“化学试剂包装及标志”的规定,化学试剂的不同等级分别用各种不同的颜色来标志,见表1。

通过解答,教会我,谢谢
C.MgCl2溶液和氨水D.盐酸和NaAlO2溶液
为什么
请问下有无同学需要H37RA的?我是做EAE模型的,上个月购买了BDDifco公司的H37RA(货号),因为购买的时候只能整盒6支购买,但我们用不了那么多,所以想问问有无同学需要的,100mg/支,800元/支或用等价试剂交换。地址广州。有需要的请私信,谢谢!
