产品说明 一般描述 Ferritin comprises 24-subunit and belongs to the ferritin-like diiron-carboxylate protein superfamily. Ferritin exists as heavy (H) and light (L) subunits. Liver ferritin is majorly L subunit and the spleen has the H submit. The L subunit is mapped to human chromosome 9q13.33 and the H subunit 11q12.3. 应用 Ferritin from human liver has been used as model protein in size-exclusion high-performance liquid chromatography technique and for synthetic nanopore translocation studies. It has also been used to test its effect on the susceptibility of shrimp (Litopenaeus vannamei) to the white spot syndrome virus. 生化/生理作用 A ubiquitous iron storage protein that plays a key role in iron metabolism. It serves as an intracellular iron reserve (particularly in spleen, liver, intestinal mucosa, and bone marrow) and functions in iron detoxification. Studies have shown that ferritin iron incorporation is mediated by a ferroxidase activity associated with ferritin H subunits and a nucleation center associated with ferritin L subunits. Release of iron from ferritin has an essential role in iron-dependent lipid peroxidation and may contribute to free radical-induced cell damage in vivo. Therefore, by binding iron, ferritin may function as an antioxidant. 外形 Solution in 10 mM Tris, 150 mM NaCl, pH 8.0, and 0.1% sodium azide. 基本信息

产品说明 一般描述 壳蛋白 24 个蛋白质亚基(脱铁铁蛋白)和核心 Fe 3+ 离子,肽 MW 为 440 kDa。回顾铁蛋白样铁储存蛋白超家族,在地球上的生命中几乎无处不在。 应用 来自马脾的铁蛋白已用于:
生化/生理作用 广泛的储铁蛋白在铁代谢中起关键作用。其用作细胞内的铁储备(特别是在脾脏、肝脏、肠粘膜和骨髓中)并参与铁解毒。 研究表明,铁蛋白铁的掺入是由与铁蛋白 H 亚基相关的铁氧化酶活性和与铁蛋白 L 亚基相关的成核中心介导的。 从铁蛋白释放铁在铁依赖性脂质过氧化中具有重要作用,并且可能在体内促成自由基诱导的细胞损伤。因此,通过结合铁,铁蛋白可以起抗氧化剂的作用。 基本信息

产品说明 一般描述 铁蛋白是一种铁贮藏蛋白,通常存在于哺乳动物的肝脏和脾脏中。铁和铁蛋白在眼内的分布基本相同。铁蛋白由重链和轻链组成。 应用 一种阳离子衍生物,用于标记带负电荷的细胞膜,以便电镜观察。
生化/生理作用 铁蛋白将铁保持在其三价铁状态 (Fe 3 + )。铁蛋白的核心具有容纳 4500 个铁分子的能力。在脊椎动物中储存铁是必不可少的。铁蛋白在无脊椎动物中也是储存和运输铁的必需物质,并在膳食铁吸收中起关键作用。 制备说明 将马脾铁蛋白与 N,N-二甲基-1,3-丙二胺 (DMPA) 偶联制备。 基本信息
