ADA Recombinant Protein

Source : Escherichia Coli. ADA Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 383 amino acids (1-363) and having a molecular mass of 42.9 kDa.The ADA is fused to a 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques. 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.

Product Specifications

Product Name Alternative

Adenosine deaminase||Adenosine aminohydrolase||ADA1||EC 3.5.4.4.

Purification

Greater than 85.0% as determined by SDS-PAGE.

Components

ADA protein 0.5mg/mL is supplied in 20mM Tris-HCL, pH-8, 1mM DTT and 20% Glycerol.

Storage Conditions

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.

Applications Notes

Specific activity is 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.
