The cell-permeant dye rhod-2, AM is a visible lightùexcitable, high affinity Ca2+ indicator. It is also available in a 1 mg packaging (R-1244).

Rhod-2是一种可见光激发的高亲和力Ca 2+ 指示剂，与其他可见光激发荧光探针如Fluo-3/4相比，Rhod-2具有长波长，更适用于检测具有较高自荧光现象的细胞和组织内钙离子水平以及检测由光感受器和笼锁钙离子螯合剂光激活导致的钙离子释放。

2025年3月11日 · Rhod-2 is most commonly used among the red fluorescent calcium indicators. However, Rhod-2 AM is only moderately fluorescent in live cells upon esterase hydrolysis, and has very small cellular calcium responses. Rhod-4™ has been developed to improve Rhod-2 cell loading and calcium response while maintaining the spectral wavelength of Rhod-2.

Rhod-2，AM，细胞可透过性 标记的钙指示剂是结合 Ca2+ 后显示荧光增加的分子。 它们可用于多种钙信号传导研究，包括自发荧光水平很高的细胞和组织中 Ca2+ 的测量以及光感受器和光活化螯合剂产生的 Ca2+ 释放的检测。

Rhod-2 (potassium salt) is a water-soluble, red fluorescent calcium indicator. It exhibits a significant shift in fluorescence intensity upon calcium binding (ex max=549 nm; calcium-free v. ex/em max=552/581 nm; calcium-bound). Unlike the UV-excitable indicators fura-2 and indo-1 (HY-D0121), there is no accompanying spectral shift.

Rhod-5N is a calcium-binding fluorescent dye composed of a BAPTA chelating group and a rhodamine fluorophore. Rhod-5N is often added to MOPS buffer to complex and indicate cation content.

The cell-impermeant dye rhod-5N, tripotassium salt is a visible lightùexcitable, low affinity Ca2+ indicator.

Rhod-2 is a high-affinity visible light excitation wavelength Ca 2+ fluorescent probe, Rhod-2, AM is an acetyl methyl ester derivative of Rhod-2, which has cell membrane permeability and can easily enter cells with simple culture.
