  Methods and materials for the imaging of cells containing active proteases such as cathepsin are disclosed. The present materials include activity based probes that bind to an enzyme and are subsequently cleaved. Cleavage results in a fluorescent signal due to removal of a quenching group which, when present on the probe causes altered or no fluorescence. The probes employ an acyloxymethyl ketone reactive group, one or more amino acids for determining specificity, a fluorophore and a quencher. The probes are cell permeable and may use, for example, a QSY7 (diarylyrhodamine) quencher and a BODIPY (bora-diaza-indecene) dye.

  揭示了用于成像含有活性蛋白酶（如半胱氨酸蛋白酶）的细胞的方法和材料。目前的材料包括结合到酶并随后被切割的活性基团探针。切割导致荧光信号的产生，因为去除了一个熄灭基团，当存在于探针上时，会导致改变或无荧光。这些探针使用酰氧甲基酮反应基团，一个或多个氨基酸用于确定特异性，一个荧光团和一个熄灭剂。这些探针具有细胞穿透性，例如，可以使用QSY7（二芳基罗丹明）熄灭剂和BODIPY（硼二氮杂环庚烯）染料。
