Description

3HA-Cdc14 (red) localization in metaphase. The protein is sequestered in the nucleolus. Metaphase is determined by spindle morphology (tubulin, green) and nuclear morphology (DAPI, blue). Image is Fig 3D, left panels, in J Cell Biol. (2011) 192: 599-614. Images in Fig 3 include CIL# 13862, 13863, 13864, 13865, 13866, 13867.

Technical Details

Cells (MATa cdc14::3HA-CDC14), grown in rich media with glucose, were fixed for 15 min in 3.7% formaldehyde and 0.1 M potassium phosphate buffer, pH 6.4. Cells were then washed twice with 0.1 M potassium phosphate buffer, pH 6.4, and resuspended in 1.2 M sorbitol in 0.12 M K2HPO4/0.033 M citric acid, pH 5.9. Fixed cells were digested with 0.1 mg/ml zymolyase-100T (US Biological) and 1/10 volume of glusulase (PerkinElmer) at 30C for 15 min, washed once, and resuspended in 1.2 M sorbitol in 0.12 M K2HPO4/0.033 M citric acid, pH 5.9. Primary antibodies were anti-HA monoclonal antibody (HA.11; 1:500) and anti-tubulin (Abcam; 1:500). Secondary antibodies were: anti-mouse Cy3 (for HA) and anti-rat FITC (for tubulin). Cells were resuspended in DAPI (1 mg/ml). Imaging was performed at 25C using a Leica DM6000 microscope equipped with a 100x/1.40 NA oil immersion objective lens, A4, L5, and TX2 filters, and a digital CCD camera (DFC350, Leica). Pictures were processed with LAS AF (leica) and ImageJ software.
