Ex 400-430 nm 紫色激发光荧光探针

Laurdan (6-Dodecanoyl-2-dimethylaminonaphthalene) 是膜透性荧光探针。它的广义极化 (GP) 定量可用于磷脂相的鉴定，对与之结合的细胞膜磷脂相具有光谱敏感性。

Bromobimane (Monobromobimane) 是一种非荧光物质，但与硫醇反应反应时生成荧光产物。Bromobimane 可被当作一种探针使用，常在临床医学上检验血液中硫化物的含量。

PB succiniMidyl ester (Ocean Blue, SE) is a fluorophore with the λ excitation emission of ~405 455 nm.

CytoCalcein Violet 450 is a fluorogenic dye used to assess cell viability. It is a cell-permeable dye that, upon entering cells, is cleaved by intracellular esterases. CytoCalcein Violet 450 is retained by living cells and displays excitation emission maxima of 405 450 nm, respectively.

TFMU-ADPr作为监测聚ATP-核糖糖水解酶(PARG)活性的底物，以其释放的荧光团直接反映PAR水解酶总活性而常用。该化合物因具备优良的反应性、通用性、稳定性及易用性，成为体外评估小分子抑制剂及研究ATP-核糖基分解代谢酶调控的首选工具。

Z-(L-Arg)-AMC is a fluorogenic substrate for trypsin, cathepsin B, and cathepsin H.1,2Upon enzymatic cleavage by trypsin, cathepsin B, or cathepsin H, 7-amino-4-methylcoumarin (AMC) is released and its fluorescence can be used to quantify trypsin, cathepsin B, and cathepsin H activity. AMC displays excitation emission maxima of 340-360 440-460 nm, respectively. 1.Zimmerman, M., Ashe, B., Yurewicz, E.C., et al.Sensitive assays for trypsin, elastase, and chymotrypsin using new fluorogenic substratesAnal.

NEP, a turn-on fluorescent probe employing the intramolecular charge transfer (ICT) mechanism, facilitates the detection of vicinal dithiol-containing proteins (VDPs). Notably, NEP exhibits exceptional selectivity towards VDPs in live cells and in vivo and manifests a robust green fluorescence signal at λ ex λ em =430 535 nm. Furthermore, NEP bears promise for the potential diagnosis and study of parkinsonism.

CytoCalcein Violet 500 is a fluorogenic dye used to assess cell viability. It is a cell-permeable dye that, upon entering cells, is cleaved by intracellular esterases. CytoCalcein Violet 500 is retained by living cells and displays excitation emission maxima of 405 500 nm, respectively.

7-Hydroxycoumarin-3-carboxylic acid, SE is the amine-reactive succinimidyl ester of 7-Hydroxycoumarin-3-carboxylic acid. This coumarin is also increasingly used to label peptides, nucleotides and carbohydrates.
