产品详情
DFHBI-1T 是一种可透过膜的 RNA 适配体激活的荧光探针 (ex/em=472 nm/507 nm)。DFHBI-1T 与 RNA 适配体 (Spinach, Spinach2, iSpinach, Broccoli) 结合并产生特定的荧光和较低的背景荧光。DFHBI-1T 可以用于活细胞中的 RNA 成像。
生物活性
DFHBI-1T is a membrane-permeable RNA aptamers-activated fluorescence probe (ex/em=472 nm/507 nm). DFHBI-1T binds to RNA aptamers (Spinach, Spinach2, iSpinach, and Broccoli) and causes specific fluorescence and lower background fluorescence. DFHBI-1T is used to image RNA in live cells.
性状
Solid
体外研究(In Vitro)
DFHBI-1T (20 μM; for 10 min) increases fluorescence in COS7 cells expressing (CGG)60-Spinach2 over DFHBI (20 μM).
Broccoli-DFHBI-1T has ex/em=472 nm/507 nm and Spinach2-DFHBI-1T has ex/em=482 nm/505 nm.
has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
