Abstract |
The association of ribosomes with the rough endoplasmic reticulum (ER) is dependent on Mg(2+). The ribosomes can be stripped from the ER by removal of Mg(2+) from the medium, resulting in a reduction in the ER membrane density and a diagnostic shift in migration when ER vesicles are analyzed by equilibrium density gradient centrifugation. Here, I describe the isolation of microsomes from Arabidopsis, followed by the use of the density shift approach in conjunction with equilibrium density gradient centrifugation as a means to diagnose whether a protein is associated with the ER. The same approach can also be used as a means to enrich for ER membranes. |
