Activity Assay Protocol
Materials:
Assay:
1. Dilute rhMMP-1 to 50 μg/mL in Assay Buffer.
2. Activate 50 μg/mL rhMMP-1 by adding APMA to a final concentration of 1 mM.
3. Incubate at 37 °C for 2 hours.
4. Dilute activated rhMMP-1 to 1 ng/μL in Assay Buffer.
5. Dilute Substrate to 20 μM in Assay Buffer.
6. Load into a black well plate 50 μL of 1 ng/μL rhMMP-1 and start the reaction by adding 50 μL of 20 μM Substrate. Include a Substrate Blank containing 50 μL Assay Buffer, 50 μL Substrate, and no rhMMP-1.
7. Read at excitiation and emission wavelengths of 320 nm and 405 nm, respectively, in kinetic mode for 5 minutes.
8. Calculate specific activity:
Specific Activity (pmol/min/μg) =Adjusted Vmax* (RFU/min) x Conversion Factor** (pmol/RFU) / amount of enzyme (μg)
*Adjusted for Substrate Blank
**Derived using calibration standard MCA-Pro-Leu-OH.
