rhod2 am

Rhod-2 AM 是一种线粒体荧光探针，λex 为 552 nm，λem 为 581 nm。

Rhod-2 (sodium 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). [1][2] Unlike the UV-excitable indicators fura-2 and indo-1 , there is no accompanying spectral shift.

Fura-2 AM is an indicator of ratiometric fluorescent Ca2+.

Rhod-5N AM is a cell-permeant acetoxymethyl ester of the fluorescent calcium indicator rhod-5N . As rhod-5N AM enters cells, it is hydrolyzed by intracellular esterases to produce rhod-5N. Rhod-5N displays a low affinity for calcium (Kd = 19 μM). Low affinity calcium indicators are particularly useful for studying compartments with high concentrations of calcium, such as endoplasmic reticulum, where high affinity dyes will be insensitive to luminal fluctuations. Rhod-5N has excitation/emission maxima of approximately 551 and 576 nm, respectively.

Mag-Fura-2 AM是一种可渗透细胞的荧光镁离子(Mg2+)指示剂，对Mg2+具有高度选择性，相较于其他二价离子(Zn2+、Cu2+和Ca2+)。其对Mg2+的选择性超过13,000倍（Mg2+Kd为1.9 nM，相对于Ca2+Kd的25 μM）。激发和发射峰值（λ）分别为369 nm和511 nm。Mag-Fura-2 AM可作为间接指示ATP消耗/产生的指标。

ING-2 AM是一种能透过细胞膜的荧光钠离子(Na+)指示剂，与钠结合(Kd=20 mM)。激发和发射峰值(λ)分别为525 nm和545 nm。该化合物对K+离子具有20倍的选择性。在体外和原位实验中用于检测实时的钠流入。

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 , there is no accompanying spectral shift.

FG 488 BAPTA-2 AM, a calcium-specific reporter dye, is utilized for detecting calcium concentration.

Calcium Green BAPTA-2 AM serves as a fluorescent indicator for calcium ions.

Rhod-FF AM is a cell-permeant acetoxymethyl ester of the fluorescent calcium indicator rhod-FF . As rhod-FF AM enters cells, it is hydrolyzed by intracellular esterases to produce rhod-FF. Rhod-FF is a difluorinated analog of the cell-impermeant calcium indicator rhod-2. It has a very low affinity for calcium (Kd = 320 μM). Low affinity calcium indicators are particularly useful for studying compartments with high concentrations of calcium, such as endoplasmic reticulum, where high affinity dyes will be insensitive to luminal fluctuations. Rhod-FF has excitation/emission maxima of approximately 552 and 580 nm, respectively.
