腺苷脱氨酶(Adenosine Deaminase，ADA)是嘌呤核苷代谢中重要的酶类，属于一种巯基酶，每分子至少含2个活性巯基，ADA能催化腺嘌呤核苷转变为次黄嘌呤核苷，再经核苷磷酸化酶作用生成次黄嘌呤，其代谢缓和终产物为尿酸，广泛分布于人体各组织中，以胸腺、脾和其他淋巴组织中含量最高，而肝、肺、肾和骨胳肌等含量低。 该试剂盒检测原理是待测样品中的ADA催化腺嘌呤核苷水解脱氨，产生次黄嘌呤核苷和铵离子，利用波氏显色法测定氨离子生成量，其反应公式为：腺苷+H₂O→次黄嘌呤+NH₃，测定640nm处吸光度，根据计算公式可得ADA活力。本产品仅用于科研领域，不适用于临床诊断或其他用途。
Adenosine Deaminase (ADA) is an important enzyme in purine nucleoside metabolism. It is a sulfhydryl enzyme containing at least two active sulfhydryl groups per molecule. ADA catalyzes the deamination of adenosine to form inosine, which is then converted to hypoxanthine by nucleoside phosphorylase. The metabolic end product of this pathway is uric acid. ADA is widely distributed in various human tissues, with the highest levels found in the thymus, spleen, and other lymphoid tissues, while lower levels are present in the liver, lungs, kidneys, and skeletal muscle. The detection principle of this kit is based on the ability of ADA in the sample to catalyze the hydrolytic deamination of adenosine, producing inosine and ammonium ions. The amount of ammonia generated is then determined using the Berthelot colorimetric reaction. The reaction formula is: Adenosine + H₂O → Inosine + NH₃. The absorbance is measured at 640 nm, and ADA activity can be calculated according to the formula. This product is intended for research use only and is not for use in diagnostic procedures or other purposes.
