Experiment[1]: | |
Sample |
Human plasma |
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. |
Reaction Conditions |
20 μM Suc-Gly-Pro-Leu-Gly-Pro-AMC |
Applications |
The FAP activity in human plasma was measured using succinyl-pentapeptide composed of SUc-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. |
Cell experiment [2]: | |
Cell lines |
Clone MC3T3-E1 cells |
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. |
Reaction Conditions |
30 μl of 2 mM Suc-Gly-Pro-Leu-Gly-Pro-AMC in 37°C for 90 min |
Applications |
When examining the activities of collagenase-like peptidase ( Suc-Gly-Pro-Leu-Gly-Pro-AMC ase) and dipeptidyl aminopeptidase (DAP) in Mc3t3-e1 in newly cloned osteoblasts with osteogenic ability, the Suc-Gly-Pro-Leu-Gly-Pro-AMC ase in MC3T3-El presented in this paper inhibited by heavy metals (Zn+2 and Cu+2), and some reagents (Mn+2, Ca+2, Mg+2, and EDTA) in creased the enzyme activity; especially, MnanEDTA increased the Suc-Gly-Pro-Leu-Gly-Pro-AMC ase activity to 8.2-fold and 23-fold[3]. |

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].
