LysoTracker Red DND-99 是一种可透过细胞的红色荧光染料,可对细胞内的酸性区室(如溶酶体)进行染色。Red DND-99 的最大激发和发射波长为 577/590 nm,可使用 TRITC 滤光片有效激发。LysoTracker 探针有多种荧光颜色可选。虽然不与细胞交联,但 LysoTracker Red DND-99 在无甲醇甲醛中固定一小段时间后有短暂保留。

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
Testosterone signaling through internalizable surface receptors in androgen receptor-free macrophages.
Authors:Benten WP,Lieberherr M,Stamm O,Wrehlke C,Guo Z,Wunderlich F
Journal:Molecular biology of the cell
PubMed ID:10512854
Testosterone acts on cells through intracellular transcription-regulating androgen receptors (ARs). Here, we show that mouse IC-21 macrophages lack the classical AR yet exhibit specific nongenomic responses to testosterone. These manifest themselves as testosterone-induced rapid increase in intracellular free [Ca(2+)], which is due to release of Ca(2+) from intracellular Ca(2+) stores. ... More

Journal:Int J Nanomedicine
PubMed ID:22904626
Nanoparticles engineered to carry both a chemotherapeutic drug and a sensitive imaging probe are valid tools for early detection of cancer cells and to monitor the cytotoxic effects of anticancer treatment simultaneously. Here we report on the effect of size (10-30 nm versus 50 nm), type of material (mesoporous silica ... More
Induction of autophagy and cell death by tamoxifen in cultured retinal pigment epithelial and photoreceptor cells.
Authors:Cho KS, Yoon YH, Choi JA, Lee SJ, Koh JY,
Journal:Invest Ophthalmol Vis Sci
PubMed ID:22786900
We investigated the mechanism of tamoxifen (TAM) retinotoxicity using human retinal pigment epithelial (RPE)-derived (ARPE-19) and photoreceptor-derived (661W) cells. Cultured ARPE-19 and 661W cells were treated with 5 to 10 µM TAM, and the resultant cell death was quantified using lactate dehydrogenase (LDH) release assay. Cellular oxidative stress was determined ... More
Streptococcal serum opacity factor increases the rate of hepatocyte uptake of human plasma high-density lipoprotein cholesterol.
Authors:Gillard BK, Rosales C, Pillai BK, Lin HY, Courtney HS, Pownall HJ,
Journal:Biochemistry
PubMed ID:20879789
Serum opacity factor (SOF), a virulence determinant of Streptococcus pyogenes, converts plasma high-density lipoproteins (HDL) to three distinct species: lipid-free apolipoprotein (apo) A-I, neo HDL, a small discoidal HDL-like particle, and a large cholesteryl ester-rich microemulsion (CERM) that contains the cholesterol esters (CE) of up to ~400000 HDL particles and ... More
