E N D
1. Southern Transfer
3. Broad Overall Objective Is Phosphoenolpyruvate carboxykinase a single or multicopy gene in E. huxleyi
4. Today’s Laboratory Objectives To become familiar with a Southern Hybridization/Analysis
a. mechanics of setting up a Southern
b. What kinds of information can be gleaned
To be able to evaluate a restriction digest
To distinguish between a partial and complete
digest of genomic DNA using agarose gel
electrophoresis
5. Theoretical Basis of Southern Definition
Southern analysis is the transfer of denatured DNA form an agarose gel to a membrane on which it can be analysed using a labelled complementary DNA or RNA probe.
Plan
1. agarose electrophoresis2. membrane transfer (capillary transfer)3. detection (chemiluminescent)
6. Loading the Agarose Gel Lane 1= Lambda Hind III Marker (negative control
Lane 2= Genomic DNA/Bam HI
Lane 3= Genomic DNA/Eco RI
Lane 4= Genomic DNA/Hind III
Lane 5= Genomic DNA/PST I
Lane 6= Genomic DNA/Eco RI + Pst I
Lane 7= Genomic DNA/Bam HI + Hind III
Lane 8= PEPCK cDNA clone (positive control)
7. Agarose Gel Electrophoresis
9. DNA Transfer Accomplished via Capillary Action
10. Hybridization and Detection
11. Next Week
PCR will be employed to create non-radioactively labelled PEPCK probes
Homologous probe will be generated
Probes will be hybridized to genomic DNA on membrane to determine which restriction fragment(s) may harbor the PEPCK gene
