الوصف: A multiweek protein purification suite, suitable for upper-division biochemistry or biotechnology undergraduate students, is described. Students work in small teams to isolate the enzyme lactate dehydrogenase (LDH) from a nontraditional tissue source, mammalian blood, using a sequence of three column chromatographic procedures: ion-exchange, size exclusion, and affinity chromatography. Protein and enzyme activity elution profiles are determined by graphical analysis of assay data collected using rapid microplate spectrophotometric assays. Students perform quantitative assays on LDH pools and use these data to build a purification table for use in evaluating the protocol. The protocol typically generates final overall fold-purifications from 1500 to 2500 and activity recoveries of 45–60%. Electrophoretic separations in both denaturing and native-gel format are analyzed both visually and by use of commercial digital analysis software to assess the isoenzyme pattern of isolated LDH and to further evaluate th...
