組織蛋白酶B (Cathepsin B, CTSB)是一種廣泛表達(dá)于溶酶體上的半胱氨酸肽鏈內(nèi)切酶，屬于木瓜蛋白酶家族的成員，廣泛存在于從病毒到哺乳動(dòng)物和人等生物體內(nèi)。可通過(guò)參與細(xì)胞凋亡、細(xì)胞外基質(zhì)降解、抗原呈遞、炎癥反應(yīng)、細(xì)胞自噬等多種病理生理過(guò)程從而參與多種疾病的發(fā)生和發(fā)展。   

       市面上常見(jiàn)的是檢測(cè)細(xì)胞裂解液中的組織蛋白酶B活性，更多研究者希望動(dòng)態(tài)檢測(cè) 活細(xì)胞 內(nèi)的組織蛋白酶B的活性，做更真實(shí)的實(shí)驗(yàn)！艾美捷科技為您推薦Immunochemistry Tech（ICT）品牌專利Magic Red系列產(chǎn)品。 

       ICT的Magic Red?檢測(cè)法使研究人員能夠在體外對(duì)細(xì)胞內(nèi)的蛋白酶活性進(jìn)行定量和監(jiān)測(cè)。

       【原理】Magic Red魔力紅底物，是細(xì)胞滲透性的，它很容易穿透細(xì)胞膜和內(nèi)部細(xì)胞器的膜——不需要裂解或滲透步驟。如果組織蛋白酶是活性的，魔紅底物被裂解，甲酰紫熒光團(tuán)將在激發(fā)時(shí)變?yōu)闊晒猓‥x/Em =592nm/628nm）。隨著酶活性的進(jìn)展和更多魔紅底物的裂解，信號(hào)將增強(qiáng)，使研究人員能夠觀察顏色隨時(shí)間的變化。樣品可通過(guò)熒光顯微鏡或熒光酶標(biāo)儀進(jìn)行分析。試劑盒中包括Hoechst 33342和吖啶橙，分別用于檢測(cè)核形態(tài)和溶酶體細(xì)胞器結(jié)構(gòu)。
