73 Bioanalytical chemistry 4. Gel Electrophoresis Required reading: Sections 9.1, 9.2.3, 9.2.4, 9.5.1, 10.1 to 10.7, 11.1 to 11.5, and 15.5 of Mikkelsen and Cortón, Bioanalytical Chemistry Some objectives for this section ⇒ You will know what DNA agarose gel electrophoresis is ⇒ You will know what the difference between normal and pulsed field electrophoresis of DNA ⇒ You will know what SDS-PAGE is. ⇒ You will understand how the basis for molecular basis for size-based separation of proteins by SDS- PAGE. ⇒ You will know what IEF is. ⇒ You will know how SDS-PAGE and IEF can be combined in 2-dimensional gel electroophoresis ⇒ You will know what a Western Blot is. ⇒ You will appreciate how these techniques can be used in the analysis of DNA and proteins.
