|Grade & Purity||> 85% pure|
|Molecular Weight||42.9 kDa (383aa), confirmed by MALDI-TOF|
|Form & Buffer||Supplied as a liquid in 20mM Tris-HCl buffer, pH 8.0, containing 20% glycerol and 1mM DTT.|
Usage & Assay Information
|Bioactivity||Specific activity: approximately >25 units/mg. Enzymatic activity was confirmed by measuring the amount of enzyme that deaminates 1.0 uM of adenosine to inosine per minute at pH 7.5 at 25 DEG C.|
Storage & Safety
|Storage||Store at 4 deg C for short term storage (1/2 weeks). Aliquot and store at -20 deg C or - 70 deg C for long term storage. Avoid repeated freeze/thaw cycles.|
|Biological Significance||ADA, also known as adenosine deaminase, catalyzes the hydrolytic deamination of adenosine and 2-deoxyadenosine. This protein plays an important role in purine metabolism and in adenosine homeostasis. ADA acts as a positive regulator of T-cell coactivation, by binding DPP4. Its interaction with DPP4 regulates lymphocyte-epithelial cell adhesion. Recombinant human ADA protein, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography.|
