Immuno-gold detection of TG2 in the nucleus of HEK293TG cells shows positive labeling. a During interphase, gold granules are localized over the euchromatin regions of the nucleus (N), whereas heterochromatin are devoid of labeling. b No particles are present at the level of the nucleolus (Nu). c General view showing the chromosomes gathered at the metaphase plate. d, e Higher magnification images showing details of the condensed chromatin clearly labeled with clusters of gold granules. Bars 0.3 μm (a, b, d, e), 3 μm (c)
