LysoBrite 溶酶體近紅外熒光探針，用于標(biāo)記活細(xì)胞的溶酶體。專有的溶解性染料可能通過溶酶體pH梯度選擇性地積聚在溶酶體中。溶質(zhì)指示劑是疏水性化合物，易于滲透完整的活細(xì)胞，并在進(jìn)入細(xì)胞后被捕獲在溶酶體中。進(jìn)入溶酶體后，LysoBrite 試劑的熒光明顯增強(qiáng)。可以使用熒光成像，高含量成像，酶標(biāo)儀熒光測定法或流式細(xì)胞術(shù)檢測熒光。 LysoBrite 橙色，紅色，深紅色和NIR試劑具有很高的光穩(wěn)定性和優(yōu)異的細(xì)胞保留性，可用于各種研究，包括細(xì)胞粘附，趨化性，多藥耐藥性，細(xì)胞活力，細(xì)胞凋亡和細(xì)胞毒性。它們適用于增殖和非增殖細(xì)胞，可用于懸浮細(xì)胞和貼壁細(xì)胞。溶酶體是細(xì)胞器，其含有酸水解酶以分解廢物和細(xì)胞碎片。溶酶體消化多余的或破舊的細(xì)胞器，食物顆粒和吞噬的病毒或細(xì)菌。溶酶體周圍的膜允許消化酶在pH4.5下工作。與微堿性胞質(zhì)溶膠（pH 7.2）相比，溶酶體的內(nèi)部是酸性的（pH 4.5-4.8）。溶酶體通過質(zhì)子泵和氯離子通道從細(xì)胞質(zhì)中泵送質(zhì)子穿過膜來維持這種pH差異。
