Hoefer DALT System Function and DescriptionIn 2-D protein electrophoresis, proteins are separated first according to isoelectric point by isoelectric focusing, most reliably on immobilized pH gradient (IPG) strips. The second dimension electrophoresis separates the proteins on the basis of their molecular mass on a slab gel containing the denaturing detergent, sodium dodecyl sulfate (SDS).The Hoefer DALT System is designed to simplify the handling of multiple second dimension gels and improve the reproducibility of the second dimension separation.
