Source HEK.
Physical Appearance and Stability Lyophilized Cystatin-C although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Cystatin-C should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity The Cystatin-C was lyophilized from 1mg/ml in 1xPBS. Greater than 95% as obsereved by SDS-PAGE.
Solubility It is recommended to reconstitute the lyophilized Cystatin-C in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The inhibitory function of Cystatin-C on papin¿s protease activity was measured by a colorimetric assay using L-BAPA as substrate. IC50 value was measured at 5-20 µg/ml (0.3-1.5 µM) with a range of 1.56-50µg/ml Cystatin-C in presence of 0.55µM papain and 0.44µM L-BAPA. The activity is typically 0.3-1.5µM IC50.
Shipping Format and Condition Lyophilized powder at room temperature.
