Application example
10 μl total protein from 9.25 x 107 cells of Saccharomyces cerevisiae extracted with 20% TCA as described below were separated on 10% SDS-PAGE and blotted 1.5h (0.5 A) to a nitrocellulose membrane (Whatman PROTRAN BA 85, 0.45 μm). Blots were blocked with 5% non-fat dry milk in TBST for 1.5h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 200 overnight at 4C° with agitation. The antibody solution was decanted and the blot was washed 3 times for 10 min in TBST at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, (AS09 602) diluted to 1:50 000 for 1h at RT with agitation. The blot was washed as above and developed for 3 min with chemiluminescent detection reagent, according to the manufacturers instructions. Exposure time was 10 min.

Open PublicationDeletion of IXR1 leads to increased Rnr3 and Rnr4 levels and decreased Sml1 levels.(A) Western blot analysis of Rnr3-HA and Rnr4 levels in wild-type (AC447-2A), ixr1-S366F (TOY619), and ixr1? (TOY621) strains before and after 2 hours treatment with 0.2 mg/L 4-nitroquinoline 1-oxide (4-NQO), 200 mM HU, or 0.02% methyl methanesulfonate (MMS). Rnr3 and Rnr4 levels were quantified in relative units (RU, levels of Rnr3 or Rnr4 divided by the levels of tubulin in corresponding sample) as described in Materials and Methods. ND – not detected. (B) Western blot analysis of Rnr2 levels in wild-type (AC447-2A) and ixr1? (TOY621) strains before treatment and after 2 hours treatment with 0.2 mg/L 4-NQO, 0.02% MMS, or 200 mM HU. (C) Western blot analysis of Sml1 levels in wild-type (W1588-4C) and ixr1? (TOY736) strains before treatment and after 2 hours treatment with 0.02% MMS. (D) Western blot analysis of Rad53 phosphorylation status in wild-type (W1588-4C) and ixr1? (TOY736) strains before treatment and after 2 hours treatment with 0.02% MMS. (E) Deletion of RAD53 but not of SML1 or DUN1 abolishes the upregulation of Rnr3 and Rnr4 levels in ixr1?. Western blot analysis of Rnr3-HA and Rnr4 levels. The following strains were analyzed: wt (AC447-2A), ixr1? (TOY732), ixr1? sml1? (TOY778), ixr1? dun1? sml1? (TOY772), and ixr1? rad53? sml1? (TOY781).
