一般描述
黄嘌呤及其衍生物天然存在于动物器官、酵母、土豆、咖啡豆和茶叶中。
黄嘌呤是一种嘌呤，可经由嘌呤代谢途径通过不同前体生成：
- 鸟嘌呤脱氨酶催化的鸟嘌呤脱氨
- 黄嘌呤氧化还原酶催化的次黄嘌呤转化
应用
本品（黄嘌呤）可作为底物测定黄嘌呤氧化酶(XOD)的抑制性。还可用于：
- 酵母培养
- 人类细胞系培养
- 重组病毒克隆为大肠杆菌中的BAC(细菌人工染色体)
生化/生理作用
黄嘌呤和黄嘌呤氧化酶可用于生成超氧自由基，测定超氧化物歧化酶的活性。
特点和优势
- 用于测定痕量金属含量（详情参见性质栏和技术规格说明书）
- 用于测定硫酸盐含量（详情参见性质栏和技术规格说明书）

Neurons can undergo a diverse range of death responses under oxidative stress, encompassing apoptosis (caspase-dependent, programmed cell death) to various forms of caspase-independent death, including necrosis. We recently showed that primary murine cortical neurons exposed acutely to hydrogen peroxide undergo

Although cells express hundreds of metalloenzymes, the mechanisms by which apoenzymes receive their metal cofactors are largely unknown. Poly(rC)-binding proteins PCBP1 and PCBP2 are multifunctional adaptor proteins that bind iron and deliver it to ferritin for storage or to prolyl
