MitoSOX Red 是一种具有特异性和细胞膜渗透性且靶向活细胞线粒体的新型荧光探针。MitoSOX Red 进入线粒体后会被超氧化物氧化,而不会被其他 ROS 或 RNS 生成系统氧化。MitoSOX Red 随后与线粒体内核酸结合,产生强红色荧光。MitoSOX Red 可以作为荧光指示剂,特异性检测超氧化物。超氧化物歧化酶 (Superoxide dismutase,SOD) 能够预防 MitoSOX Red 氧化。
Texas Red-X succinimidyl ester,suitable for high bright Red succinimidyl fluorescence excitation emission maximum ~ 595 615 nm.This reactive dye contains additional amino hexanoic acid and succinimide groups.This interval helps to distinguish between the
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.
Protein arginine deiminases (PADs) catalyze the posttranslational modification of arginine residues on proteins to form citrulline, which plays a large role in regulating gene expression. Abnormally high PAD activity has been observed in a host of human diseases. Citrulline-specific probe-rhodamine is a highly sensitive, rhodamine phenylglyoxal-based fluorophore that specifically detects protein citrullination via a chemoselective reaction between glyoxal and citrulline. This chemical probe (comprised of a single isomer) is capable of reacting with any citrulline-containing protein and can be analyzed with fluorescent imaging (excitation 532 nm; emission 580 nm). When added at 100 μM for 30 minutes at acidic pH, this probe has a reported limit of detection of ~10 ng for citrullinated histone H3 and ~1 ng for autodeiminated PAD4.
PA Janelia Fluor 549, SE (PA-JF549-NHS) is a bright photoactivatable fluorophore of JF549, SE (JF549, NHS). JF549, SE (JF549, NHS) is a fluorescent dye with the absorption maximum (λab (max)) of 549 nm and emission maximum (λem (max)) of 571 nm.
Janelia Fluor 585, SE (JF585, SE) is an orange fluorescent dye containing an NHS ester that can be conjugated with primary amine groups. Janelia Fluor 585, SE can be used immediately for structured illumination (SIM) and stimulated emission depletion (STED) imaging and could be converted to photoactivatable derivative for single-molecule localization microscopy (SMLM) experiments.
Phalloidin-TRITC is a TRITC labeled, red fluorescence probe for F-actin . Phalloidin, bound to actin filaments, reacts covalently with amino acids Glu-llT, Met-ll9, and Met355, which are very close to the nucleotide binding site.
RB-OPD, also known as NO-red, is a fluorescent probe that combines o-phenylenediamine (OPD) and rhodamine nitric oxide (NO). With a λex of 550 nm and a λem of 590 nm, it exhibits exceptional sensitivity and selectivity.
Rhod-5N is a low affinity fluorescent calcium probe (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-5N has excitation emission maxima of approximately 551 and 576 nm, respectively
