Detection ofprotease activity in 96-well plates using a polymer-conjugated fluorogenic probes |
초록 |
The extent of matrix metalloproteinases(MMPs) detected in biological samples provides important clinical information for diagnosis, prognosis, and therapeutic monitoring of various diseases relating with MMPs. We developed a new high-throughput MMP diagnostic kit (MMP-D-KIT) based on a 96-well plate by immobilizing MMP-13 specific fluorogenic peptide probes, which is a pair consisting of a near-infrared fluorophore and a quencher, on to glycol chitosan polymer anchored 96-will plate. When MMP enzymes were simply added in a MMP-D-KIT, the fluorescence of each well was recovered and the fluorescence intensity showed distinct difference within minutes through NIR fluorescence imaging system. Furthermore, recovery of NIR fluorescent signals in MMP-D-KIT was proportional to MMP’s concentration. Additionally, the MMP-D-KIT was used to detect MMP activity in synovial fluid from 12 OA patients. The fluorescence intensity measured using MMP-D-KIT decidedly correlate with the progression of OA. |
