LysoTracker Blue DND-22 是一种可透过细胞、不可固定的蓝色荧光染料,可对活细胞内的酸性区室(如溶酶体)进行染色。Blue DND-22 的最大激发和发射波长为 373/422 nm,可使用 DAPI 滤光片有效激发。LysoTracker 探针有多种荧光颜色可选。

酸性细胞器的简单、高度特异性的一步染色和示踪
LysoTracker 探针由一种与弱碱结合的荧光基团组成,仅在中性 pH 条件下被部分质子化。在中性电荷状态下,LysoTracker 探针可自由扩散穿过活细胞的完整质膜。 由于溶酶体内固有的酸性,在扩散进入溶酶体时,弱碱性基团会被质子化。在这种带电状态下,探针不易扩散穿过细胞器膜,为酸性细胞器(如溶酶体)的独特染色提供了局部积累。LysoTracker 探针在纳摩尔浓度下有效,对酸性细胞器具有高度选择性,并提供不依赖抗体检测的简单一步染色。

由于产生并储存消化酶(水解酶),溶酶体为酸性。溶酶体的酸性环境能够降解碳水化合物、脂质、核酸和多肽。细胞外蛋白、病毒或细菌还可被内化和运输至溶酶体,通过溶酶体蛋白水解途径降解。此外,错误折叠的蛋白质或受损的细胞器会通过诱导自噬成为溶酶体降解的靶标。自噬对细胞分化、营养剥夺期间的生存和正常生长控制都很重要。各种随酸性环境变化的探针可利用溶酶体内固有的酸性,以及生物合成或发病过程中 pH 值的任何变化。LysoTracker 产品可为酸性环境的活细胞染色提供荧光检测,还可用于标记和示踪溶酶体等酸性细胞器。

Abstract
Quantitative measurement of mast cell degranulation using a novel flow cytometric annexin-V binding assay.
Authors:Demo SD, Masuda E, Rossi AB, Throndset BT, Gerard AL, Chan EH, Armstrong RJ, Fox BP, Lorens JB, Payan DG, Scheller RH, Fisher JM
Journal:Cytometry
PubMed ID:10404150
'BACKGROUND: Mast cells are primary mediators of allergic inflammation. Antigen-mediated crosslinking of their cell surface immunoglobulin E (IgE) receptors results in degranulation and the release of proinflammatory mediators including histamine, tumor necrosis factor-alpha, and leukotrienes. METHODS: Mast cells were stimulated to degranulate by using either IgE crosslinking or ionophore treatment. ... More
Determination of intracellular organelles implicated in daunorubicin cytoplasmic sequestration in multidrug-resistant MCF-7 cells using fluorescence microscopy image analysis.

'BACKGROUND: Anthracycline resistance is known to be mediated by P-glycoprotein (P-gp) or multidrug-resistance related protein (MRP) as well as intracellular sequestration of drugs. METHODS: The resistance phenotype of doxorubicin-selected MCF-7(DXR) human breast adenocarcinoma cell line was characterized by cellular and nuclear daunorubicin efflux, P-gp and MRP expression and apoptosis induction. ... More
In situ assessment of cell viability.

Journal:Cell Transplant
PubMed ID:9786064
'Cryobiological studies of tissues often require the simultaneous assessment of tissue structure and in situ cellular function. Localization of damage during cryopreservation occurs as a consequence of tissue structure and morphology and as a result of biophysical constraints imposed by diffusion and heat transfer. This study used five experimental model ... More
Higher order Rab programming in phagolysosome biogenesis.
Authors:Roberts EA, Chua J, Kyei GB, Deretic V
Journal:J Cell Biol
PubMed ID:16982798
'Phagosomes offer kinetically and morphologically tractable organelles to dissect the control of phagolysosome biogenesis by Rab GTPases. Model phagosomes harboring latex beads undergo a coordinated Rab5-Rab7 exchange, which is akin to the process of endosomal Rab conversion, the control mechanisms of which are unknown. In the process of blocking phagosomal ... More
