應用

次黄嘌呤是一种营养添加剂，适用于细菌、寄生虫（恶性疟原虫）和动物细胞等多种细胞培养应用。 次黄嘌呤是杂交瘤技术所用选择培养基的组分。
次黄嘌呤已被用于：
  • 在氧嗪酸钾(PO)诱导的小鼠高尿酸血症模型中，灌胃并评估体内巴氏全脂牛奶中黄嘌呤氧化酶(XO)的活性
  • 作为Iscove改良的DMEM培养基(IMDM)的补充剂，用于培养体外细胞株（EL-1细胞）
  • 作为高效液相色谱-紫外法(HPLC-UV)的纯标准品，用于定量分析玻璃体液样本中的次黄嘌呤以推断死亡时间

生化／生理作用

次黄嘌呤(Hypoxanthine)是嘌呤代谢的中间产物。它在一些转运RNA(tRNA)中作为反密码子′-碱基发挥重要作用。结构虽然与鸟嘌呤(Gua)类似，但C(2)位没有环外氨基。它可作为底物，用于次黄嘌呤-鸟嘌呤磷酸核糖转移酶的特异性和动力学研究。

Uric Acid in Cell Culture

Uric acid is not a direct additive to any of the classical cell culture media. However, it is present in animal sera. Consequently, uric acid is typically present in complete serum-supplemented classical cell culture systems.

HPLC Analysis of Xanthines on Purospher® STAR RP-18 endcapped

Xanthine is a purine base found in most human body tissues and fluids as well as in other organisms. Methylated xanthines (methylxanthines), which include caffeine, paraxanthine, theobromine, and theophylline, commonly used for their effects as mild stiµlants and as bronchodilators, notably in the treatment of asthma symptoms. This application shows the efficient separation of several common xanthines and may be applied their analysis in any number of desired matrices.
