Em 431-450 nm 蓝色发射光荧光探针

4-MUNANA(4-Methylumbelliferyl-N-acetyl-α-D-Neuraminic Acid sodium salt) 是用于神经氨酸酶 (neuraminidase) 活性测定的荧光底物，是神经氨酸酶底物类似物。

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。

Direct Black 38 (Chlorazol Black E) 是一种黑色偶氮染料，可吸收各种颜色的光线，常用于纺织工业。Direct Black 38 具有遗传毒性，可在大鼠肝脏和骨髓微核中诱导计划外 DNA 合成。

7-Hydroxy-4-methylcoumarin-3-acetic acid, SE 是一种有用的有机化合物，可用于生命科学领域的相关研究。其产品编号为 T67683，CAS号为 96735-88-5。

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.

2-(7-Hydroxy-2-oxo-2H-chromen-4-yl)acetic acid 是一种有用的有机化合物，可用于生命科学领域的相关研究。其产品编号为 T65277，CAS号为 6950-82-9。

Indo-1 AM is an indicator of fluorescent Ca2+ (λex=340 nm, λem=405 485 nm).

4-Methylumbelliferyl β-D-Galactopyranoside-6-sulfate (sodium salt) (4-MU-Gal-6S) is a fluorogenic substrate used to quantify N-acetylgalactosamine-6-sulphatase (GALNS) activity. 4-MU-Gal-6S is cleaved by GALNS to release the fluorescent moiety 4-MU. 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high (7.12-10.3) pH, respectively, and an emission maximum ranging from 445 to 455 nM, increasing as pH decreases. It has been used to detect Morquio disease type A, a lysosomal storage disorder in which GALNS is deficient. 4-MU-Gal-6S can be used to assess GALNS activity in a very small blood volume to determine the extent of deficiency.

7-Methoxycoumarin-3-carboxylic acid is used for HPLC derivatization and for developing FRET probes to analyze protease activities.
