产品使用指南

摩尔计算器

Rhodamine B hydrazide 是一种良好的亚硫酸盐探针，具有无色、无荧光特性。Rhodamine B hydrazide 产生的荧光强度与亚硫酸盐浓度有关（5-800 ng/mL；检测限=1.4 ng/mL (3σ)）。亚硫酸盐还原溶解氧，产生超氧自由基，超氧自由基则与 Rhodamine B hydrazide 结合形成荧光产物 Rhodamine B。Rhodamine B hydrazide 在亚硫酸盐存在下发出荧光，这种荧光可通过 Tween 80 表面活性剂胶束增强。Rhodamine B hydrazide 在 554 nm 处具有最大吸收，在 574 nm 处具有最大荧光发射。

生物活性

Rhodamine B hydrazide is a good probe for sulfite, with colorless and non-fluorescent properties. While the emission is related to the concentration of sulfite (5-800 ng/mL; detection limit=1.4 ng/mL (3σ)). Sulfite reduces dissolved oxygen to yield superoxide radicals, which binds to Rhodamine B hydrazide to form Rhodamine B. Rhodamine B hydrazide gives Rhodamine B-like fluorescence in the presence of sulfite, which is enhanced by Tween 80 surfactant micelles. Rhodamine B hydrazide has an absorption maximum at 554 nm and a fluorescence emission maximum at 574 nm[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
