HuH-7 cells are an immortalized cultured cell line derived from hepatic carcinoma. Cells were grown on 1.5 glass coverslips, fixed with formaldehyde and glutareldehyde, extracted, and labeled for fluorescence microscopy with commercial antibodies to alpha- or beta-tubulin and propidium iodide. The coverslip was mounted on a slide in PBS and glycerol with n-propyl gallate as an antifading agent. Imaging was performed with a BioRad MRC 600 laser scanning confocal microscope with a Kr/Ar laser with lines at 488 and 568 nm. The microscope was a fixed tube length Nikon Diaphot with 60X N.A. 1.4 phase 3 optics. Z series was collected at 0.2 um step sizes. The original XY spatial scale has been lost.
