LE 28 is a selective and activity-dependent legumain probe. LE 28 becomes fluorescent only upon binding active legumain. LE 28 can be used for research of cancers and inflammatory diseases[1]. | [in vivo]
LE 28 (2 mg/kg, i.v.) produces specific signal in the kidney of mice[1].
LE 28 (2 mg/kg, i.v.) signal is detected around the periphery of the tumors at 30 min, with maximal contrast between tumor and normal tissue achieved after 7 hours in HCT-116 xenograft tumor model[1].
| Animal Model: | HCT-116 xenograft tumor model[1] | | Dosage: | 2 mg/kg | | Administration: | i.v. | | Result: | Detected the signal around the periphery of the tumors in as early as 30 min, with maximal contrast between tumor and normal tissue achieved after seven hours, and the signal remained constant up to 28 h. |
