LysoTracker Yellow HCK-123 是一种可透过细胞、不可固定的黄色荧光染料,可对细胞内的酸性区室(如溶酶体)进行染色。黄色 HCK-123 的最大激发和发射波长为 465/535 nm。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
Insect lipoprotein follows a transferrin-like recycling pathway that is mediated by the insect LDL receptor homologue.
Authors:Van Hoof D, Rodenburg KW, Van der Horst DJ
Journal:J Cell Sci
PubMed ID:12356906
'The lipoprotein of insects, high-density lipophorin (HDLp), is homologous to that of mammalian low-density lipoprotein (LDL) with respect to its apolipoprotein structure. Moreover, an endocytic receptor for HDLp has been identified (insect lipophorin receptor, iLR) that is homologus to the LDL receptor. We transfected LDL-receptor-expressing CHO cells with iLR cDNA ... More
Distinct pathways of antigen uptake and intracellular routing in CD4 and CD8 T cell activation.
Authors:Burgdorf S, Kautz A, Böhnert V, Knolle PA, Kurts C
Journal:Science
PubMed ID:17463291
The mechanisms that allow antigen-presenting cells (APCs) to selectively present extracellular antigen to CD8+ effector T cells (cross-presentation) or to CD4+ T helper cells are not fully resolved. We demonstrated that APCs use distinct endocytosis mechanisms to simultaneously introduce soluble antigen into separate intracellular compartments, which were dedicated to presentation ... More
Cholesterol level regulates endosome motility via Rab proteins.
Authors:Chen H, Yang J, Low PS, Cheng JX,
Journal:Biophys J
PubMed ID:17981910
The role of cholesterol in the regulation of endosome motility was investigated by monitoring the intracellular trafficking of endocytosed folate receptors (FRs) labeled with fluorescent folate conjugates. Real-time fluorescence imaging of HeLa cells transfected with green fluorescent protein-tubulin revealed that FR-containing endosomes migrate along microtubules. Moreover, microinjection with antibodies that ... More
Dynamics and mechanisms of quantum dot nanoparticle cellular uptake.
Authors:Xiao Y, Forry SP, Gao X, Holbrook RD, Telford WG, Tona A,
Journal:J Nanobiotechnology
PubMed ID:20550705
ABSTRACT: BACKGROUND: The rapid growth of the nanotechnology industry and the wide application of various nanomaterials have raised concerns over their impact on the environment and human health. Yet little is known about the mechanism of cellular uptake and cytotoxicity of nanoparticles. An array of nanomaterials has recently been introduced ... More
Plasma membrane associated location of sulfonated meso-tetraphenylporphyrins of different hydrophilicity probed by total internal reflection fluorescence spectroscopy.
Authors:Sailer R, Strauss WS, Emmert H, Stock K, Steiner R, Schneckenburger H
Journal:Photochem Photobiol
PubMed ID:10824598
Sulfonated meso-tetraphenylporphyrins of different hydrophilicity were microspectrofluorimetrically examined in endothelial cells using total internal reflection (TIR) illumination or epi-illumination. Since the penetration depth of the evanescent field during TIR illumination is limited to a few hundred nanometers, photosensitizers were almost selectively examined in close vicinity to the plasma membrane. Pronounced ... More
