Suc-Gly-Pro-Leu-Gly-Pro-AMC, a highly sensitive, fluorogenic substrate for thimet oligopeptidase as well as for post-proline cleaving enzyme (prolyl endopeptidase) [1].
The FAP activity in human plasma was measured using succinyl-pentapeptide composed of SUch-Gly-pro-Leu-Gly-pro-AMC, which contains two FAP cleavage sites.Only the cleavage between the last proline residue and the AMC group releases the fluorescent AMC group, resulting in a fluorescence reading, and the FAP activity of the measured samples ranges from 1.3 to 7 nM/min/ μL[2].
When each cell suspension was reacted with BODIPY FL casein and seven kinds of peptide-MCA substrates, respectively, a remarkable difference in hydrolytic activities toward Suc-GPLGP-MCA, a substrate toward collagenase-like peptidase, was observed between the constructs: Lc-Triad-displaying cells showed higher catalytic activity than Lc-WT-displaying cells[5].
In Male BALB/c mice ，using Suc-Gly-Pro-Leu-Gly-Pro-AMC test，no significant accumulations of other proteinases, such as matrix metalloproteinases, cathepsin D, and serine proteinases, were determined[3].Suc-GPLGP-MCA is hydro- lyzed at the Leu-Gly bond by CL-peptidase. The CL-peptidase activity in synovial fluid was significantly higher in patients with rheumatoid arthritis (RA) than in patients with osteoarthritis (OA) and in arthropathy-free controls[4].

使用由 SUch-Gly-pro-Leu-Gly-pro-AMC 组成的琥珀酰五肽测定人血浆中的 FAP 活性，其中包含两个 FAP 切割位点。仅最后一个脯氨酸残基和 AMC 基团之间的切割释放荧光AMC基团，产生荧光读数，被测样品的FAP活性范围为1.3-7 nM/min/μL[2]。
当每种细胞悬浮液分别与 BODIPY FL 酪蛋白和七种肽-MCA 底物反应时，在构建体之间观察到对 Suc-GPLGP-MCA（胶原酶样肽酶的底物）的水解活性存在显着差异: Lc-Triad展示细胞比Lc-WT展示细胞表现出更高的催化活性[5].
在雄性 BALB/c 小鼠中，使用 Suc-Gly-Pro-Leu-Gly-Pro-AMC 试验，未检测到其他蛋白酶如基质金属蛋白酶、组织蛋白酶 D 和丝氨酸蛋白酶的显着积累 [3].Suc-GPLGP-MCA 在 Leu-Gly 键处被 CL-肽酶水解。类风湿关节炎（RA）患者滑液中的CL-肽酶活性显着高于骨关节炎（OA）患者和无关节病的对照组[4]。

Preparation Method |
In each reaction with a total volume of 100 μl of solution, 20 μl of human plasma was added to assay buffer consisting of 20 mM Tris/HCl, pH 8.0, 0.1 M NaCl and 1 mM EDTA. The substrate（Suc-Gly-Pro-Leu-Gly-Pro-AMC） was added to a final concentration of 20 μM. The samples were incubated at 37 °C, and fluorescence was recorded using a microtiter-plate fluorometer with an excitation wavelength of 360 nm and an emission wavelength at 460 nm. |

Preparation Method |
Samples of 5 x 104 cells were cultured in 35-mm plastic dishes for 5 days. After the cultures were washed with 0.02 M Ca+2- , Mg+2-free phosphate buffer (pH 7.2), they were scraped off from the dishes and homogenized in the same buffer with a glass teflon homogenizer. The homogenate was used for the assay of Suc-Gly-Pro-Leu-Gly-Pro-AMC ase and DAP activities. |
