Large-scale isolation of human erythrocyte Ca2+-transport ATPase
The Biochemical Journal
|October 1, 1982
Abstract:
A rapid procedure for preparing large quantities of purified erythrocyte Ca2+-transport ATPase is presented. The method involves: (1) fast preparation of calmodulin-deficient, essentially haemoglobin-free, erythrocyte membranes by molecular filtration using Pellicon filters; (2) solubilization of membrane proteins by deoxycholate; and (3) a batch procedure using calmodulin-Sepharose 4B gel for purification of Ca2+-transport ATPase.
