Content

Part 1: In the first part basic principles and methods that are widely used in molecular genetics are discussed. These include: Isolation, analyis and cloning of nucleic acids. Cloning in bacteria and yeast. Construction of libraries. Polymerase chain reaction and selected applications. Directed mutagenesis. Analysis of gene structure and expression. Part 2: Isolation of cDNA clones - how to find the right one? Differential expression analysis - microarrays, differential display, etc. Dealing with whole genomes - microsatellites, modern genetic maps, positional cloning, ESTs, FISH. Transgenic and "knockout" organisms. Production of "recombinant" proteins. Recent developments with promise for the future. Part 3: I) Antibody phage technology: the antibody molecule V genes, CDRs, basics of antibody engineering principles of phage display phagemid and phage vectors antibody libraries phage display selection methodologies other phage libraries (peptides, globular proteins, enzymes) alternative screening/selection methodologies intrabodies, plantibodies robotization by-passing antibody technology II) Proteins: chemical modification and biomolecular interactions chemical modifications of proteins labeling proteins with photoactive molecules homo- and hetero-dimerisation of proteins radioactive labeling of proteins (alpha, beta and gamma emitters) kinetic association and dissociation constants affinity constant: definition and its experimental measurement III) Proteomics and related technologies Immobilised pH gradients 2D-PAGE Prefractionation/Prefiltration (plasma) 2D-DIGE Mass-spectrometry and protein identification (tryptic digests, MALDI-TOF, LC-MS-MS etc.) Isotope-coded affinity tags (ICAT) Functional Proteomics (probing serine hydrolases, identifying protein-protein interactions) In vivo Proteomics Protein arrays, antibody arrays Biosensor technologies (BIAcore)
