Abstract
Here, we demonstrate that pancreatic microsomal membranes from pigs, sheep, or cattle destined for human consumption can be used as a valuable and ethically correct alternative to dog microsomes for cell-free protein translocation. By adding adequate ribonuclease (RNase) inhibitors to the membrane fraction, successful in vitro co-translational translocation of wild-type and chimeric pre-prolactin into the lumen of rough microsomes was obtained. In addition, the human type I integral membrane proteins CD4 and VCAM-1 were efficiently glycosylated in RNase-treated microsomes. Thus, RNase-neutralized pancreatic membrane fractions from pig, cow, or sheep are a cheap, easily accessible, and fulfilling alternative to canine microsomes.
