A detectable substrate for aldehyde dehydrogenase (ALDH) can include a radiolabel. When acted upon by ALDH in an ALDH-expressing cell, e.g., cancer cells, the radiolabeled substrate accumulates in the ALDH-expressing cell. ALDH-expressing cells can be distinguished by the accumulated radioactivity. When combined with suitable imaging technique, the detectable substrate can be used for in vivo imaging of cancer cells.
一种可检测的
醛脱氢酶(ALDH)底物可以包含放射性标记。在ALDH表达细胞(例如癌细胞)中被ALDH作用时,放射性标记的底物会在ALDH表达细胞中积累。ALDH表达细胞可以通过积累的放射性活性来区分。结合适当的成像技术,可将可检测的底物用于体内癌细胞成像。
