产品详情
简单介绍：
ADA Human
详情介绍：
Catalogue number
ENZ-147
Synonyms
Adenosine deaminase, Adenosine aminohydrolase, ADA1, EC 3.5.4.4.
Introduction
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.
Description
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.

Source
Escherichia Coli.
Physical Appearance
ADA is supplied as a sterile filtered clear solution.
Formulation
ADA protein 0.5mg/ml is supplied in 20mM Tris-HCL, pH-8, 1mM DTT and 20% Glycerol.
Stability
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.
