LysoTracker Deep Red 染色剂是一种可透过细胞、不可固定的红色荧光染料,可对细胞内的酸性区室(如溶酶体)进行染色。Deep Red 染色剂的最大激发和发射波长为 647/668 nm,可使用 Cy5 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
A helminth cathelicidin-like protein suppresses antigen processing and presentation in macrophages via inhibition of lysosomal vATPase.
Authors:Robinson MW, Alvarado R, To J, Hutchinson AT, Dowdell SN, Lund M, Turnbull L, Whitchurch CB, O'Brien BA, Dalton JP, Donnelly S,
Journal:FASEB J
PubMed ID:22872675
'We previously reported the identification of a novel family of immunomodulatory proteins, termed helminth defense molecules (HDMs), that are secreted by medically important trematode parasites. Since HDMs share biochemical, structural, and functional characteristics with mammalian cathelicidin-like host defense peptides (HDPs), we proposed that HDMs modulate the immune response via molecular ... More
Caveolin targeting to late endosome/lysosomal membranes is induced by perturbations of lysosomal pH and cholesterol content.

'Caveolin-1 is an integral membrane protein of plasma membrane caveolae. Here we report that caveolin-1 collects at the cytosolic surface of lysosomal membranes when cells are serum starved. This is due to an elevation of the intralysosomal pH, since ionophores and proton pump inhibitors that dissipate the lysosomal pH gradient ... More

'NK-cell leukemia is a clonal expansion of NK cells. The illness can occur in an aggressive or chronic form. We studied cell lines from human and rat NK-cell leukemias (aggressive NK-cell leukemia) as well as samples from patients with chronic NK-cell leukemia to investigate pathogenic mechanisms. Here we report that ... More
