Phase differential enhancement of FLIM to distinguish FRET components of a biosensor for monitoring molecular activity of Membrane Type 1 Matrix Metalloproteinase in live cells.
荧光寿命分辨成像显微镜(FLIM)已被用于监测蛋白水解酶膜型1基质金属蛋白酶(MT1-MMP)的酶活性,该酶参与细胞外基质蛋白降解及细胞迁移等过程,其表达升高与肿瘤细胞侵袭潜能正相关。本文利用一种基于 Förster 共振能量转移(FRET)的基因编码生物传感器,在体外及活 HeLa 和 HT1080 细胞中检测 MT1-MMP 的...
