Product Name: L-Asparaginase

Product No: ENZ-287

Synonym(s): L-Asparaginase

Description: L-Asparaginase was purified from E. coli ASI.357

Protein Derived From: Escherichia coli.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

Purity: Greater than 96.0% as determined by SDS-PAGE.

Stability: Lyophilized L-Asparaginase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution L-Asparaginase should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.

Biological Activity: One IU of L- Asparaginase is defined as that amount of enzyme required to generate 1 micromol of ammonia per minute at pH 7.3 and 37C.

Solubility: It is recommended to reconstitute the lyophilized L-Asparaginase in 18M-cm H2O at 1mg/ml.

Specific Activity: 269 IU/mg.

Unit Definition: One unit of enzyme catalyzes hydrolyzation of 10 nanomoles of dUTP to dUMP in one hour at 85 Centigrade.
