Product Description
Adenosine Deaminase Human Recombinant
Overview
ADA catalyzes the hydrolytic deamination of adenosine and 2-deoxyadenosine. ADA has a vital part in purine metabolism and in adenosine homeostasis. ADA performs as a positive regulator of T-cell coactivation, by binding DPP4 which regulates lymphocyte-epithelial cell adhesion.
Biological Activity
Specific activity: approximately >25 units/mg. Enzymatic activity was confirmed by measuring the amount of enzyme that deaminates 1.0 umol of adenosine to inosine per minute at pH 7.5 at 25C.
Specifications
| Purity | Greater than 85.0% as determined by SDS-PAGE. |
|---|---|
| Formulation | ADA protein 0.5mg/ml is supplied in 20mM Tris-HCL, pH-8, 1mM DTT and 20% Glycerol. |
| Storage | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
| Expression System | Escherichia Coli. |
