DryTransfer干法蛋白转膜
Trans-Bot SD Assembly1. Prepare the transfer buffer.2. Following electrophoresis, equilibrate the gels in transfer buffer. Equilibration facilitates the removal of electrophoresis buffer salts and detergents. The length of time required for equilibration is dependent on the gel thickness. For example, 15 min. for a 0.75 mm SDS-PAGE gel.3. Cut the membrane to the dimensions of the gel. Wet the ......阅读全文
