Fig. 5. Colocalisation of XBub3 and XMad2 at kinetochores in nocodazole-treated XTC
cells. XTC cells grown on coverslips were treated with 10 µg/ml nocodazole
for 4 hours and then fixed and stained using rabbit XMad2 antibody (XMad2) and
a sheep XBub3 peptide antibody (XBub3). The antibodies were detected using
fluorescence-labelled secondary antibodies (XBub3 is green, XMad2 is red).
Chromosomes were detected by mounting the coverslips in medium containing DAPI
(DNA). The merge of all three fluorescent images is also shown. Bar, 10
µm.
