材料与方法用Teale(1959)的方法从人血红蛋白中制备脱辅基血红蛋白。其浓度通过使用E= 0.85 mL mg-1 cm-1在280 nm下在0.1 M NaOH中进行比色测定。将pH 7.0的2 M磷酸盐缓冲液与溶解在0.01M NaOH中的1.5化学计量当量的Zn-血红素重新混合。将混合物在冷的环境中放置过夜,然后通过用0.01M磷酸盐缓冲液(pH6.4)平衡的Sephadex G-25过滤,并吸附在用相同缓冲液平衡的CM-纤维素柱上。在pH 6.1的0.01 M磷酸盐缓冲液和pH 7.5的0.04 M磷酸盐缓冲液上以等体积进行梯度洗脱。收集主要部分并储存在寒冷、黑暗中。
Materials and MethodsApohemoglobin was prepared from human hemoglobin by the method of Teale (1959). Its concentration was determined spectrophotometrically by using E= 0.85 mL mg" 1 cm" 1 at 280 nm in 0.1 M NaOH.Apohemoglobin in0. 2 M phosphate buffer at pH 7.0 was recombined with 1.5 stoichiometric equivalents of Zn-heme dissolved in 0.01 M NaOH. The mixture was left overnight in the cold, and then it was filtered through Sephadex G-25 equilibrated with 0.01 M phosphate buffer at pH 6.4 and absorbed on a CM-cellulose column equilibrated with the same buffer. A gradient elution was performed with equal volumes on 0.01 M phosphate buffer at pH 6.1 and 0.04 phosphate buffer at pH 7.5. The main fraction was collected and stored in the cold, in the dark.
