Scientific Skills
? Use of E. coli for recombinant DNA: small and large- scale preparation of plasmid /genomic DNA; qualitative/quantitative analysis and isolation of restriction fragments in agarose gels; enzymatic treatments for DNA manipulations (restriction endonucleases, polymerases, phosphatases, kinases, ligases, ribonucleases, etc); clonation / subclonation.
? Nucleic acids hibridization (Southern, dot blot analysis): extensive knowledge in use of both radioactive ( P32) and DIG-labeled probes.
? PCR techniques: enzymatic amplification of DNA with cloning purposes, from plasmidic and genomic DNA; molecular cloning methods for PCR products (generation of T-A overhangs; generation of cohesive ends by introduction of flanking restriction sites, etc.). Design of DNA fragments for gene disruptions and PCR genotypic analysis of knock- out mutations. RT-PCR, knowledge of the basic methods.
? Protein biochemistry and analytical biochemistry: extensive experience in protein extraction, inmunoprecipitations, GST pull downs, SDS-PAGE and Western blot analysis. Experience in detection of ubiquitin-protein conjugates. S35 labeling and pulse-chase analysis. Coomassie, silver staining. Bradford and other quantitative methods. Differential centrifugation and membrane fractionation (gradients). Biochemical assays for enzymatic activity analyses of some specific proteins: beta-galactosidase, proteases, polyphosphate hydrolases; membrane permeases transport measurements using C14- radiolabeled molecules, using scintillation counter. Bioluminescence assay kits to determine amounts of nucleosides/ nucleotides in yeast cell extracts. Good experience using Wallac-type fluorimeter machines to perform microarray enzymatic assays in multi-welled plates.
? Genetic and molecular methods involving the yeast Saccharomyces cerevisiae: Yeast media, cloning vectors, growth and manipulation methods: determination cell density, phenotype by replica plating, diploid construction, sporulation and tetrads dissection. Genetic transformation. Manipulation of yeast cloned DNA: integrative transformation, gene replacement, integrative disruption, plasmid shuffling for screening of conditional lethal mutation, cloning of yeast genes by complementation. Quantitative mating analyses and random spore analyses; halo tests with a-pheromone. Screening of phenotypes for mutants: auxotrophies, carbon and nitrogen utilization defects, slow growth, pseudohyphae formation, respiratory defects (i.e. petites); sensitivity to temperature, drugs, salts, heavy metals; stress response defects: sensitivity to heat-shock, starvation, osmotic changes, etc.
? Microscopy: subcellular localization of proteins, by immunofluorescence and fluorescent protein labeling. Extensive knowledge of fluorescent confocal microscopy methodologies.
? Computers: Complete working knowledge of both PC and MAC’s operating systems. Sequence Analysis & Genome Browsers.
