一般描述
本品功能未测试过是否与天然制剂(未冻干亚铁血红蛋白)等效。
血红蛋白A2(HBA2)定位于人染色体16p13.3上。 HBA2是一种少量的血红蛋白成分,包含两条α 和δ 链。
血红蛋白是红细胞的主要成分,也是其表现为红色的原因。其在红细胞中的正常浓度为34%。由于它能够将氧从肺部输送到身体组织,并促进二氧化碳的返回运输,因此血红蛋白是脊椎动物最重要的呼吸蛋白。
应用
亚铁稳定的人血红蛋白A2已被用作反相高效液相色谱中的参考品,可用于对δ -珠蛋白洗脱曲线进行定量。 它还被用作同位素稀释质谱(IDMS)测量的校准试剂。
血红蛋白A2可用于通过时间分辨免疫荧光测定法对胎儿血红蛋白进行测定。
生化/生理作用
在β-地中海贫血性状患者中观察到血红蛋白A2(HBA2)的水平升高。
包装
包装尺寸表示通过Drabkin, D.L., J. Biol. Chem., 164, 703 (1946).所报道方法测定的血红蛋白量。
制备说明
当用缓冲液进行溶解时,可得到> 90%的铁血红蛋白。
