Immunohistochemical detection of Chop and apoptosis in islets of male Ins2WT/WTChop+/+, Ins2WT/C96YChop+/+, and Ins2WT/C96YChop–/– mice. (a) Immunostaining of insulin and Chop. The pancreata from Ins2WT/C96YChop+/+ and Ins2WT/C96YChop–/– male mice at 4 weeks of age were fixed and then costained for insulin (red) and Chop (green). Phase-contrast images and fluorescence images of the same fields are shown. Original magnification: ×100. (b) Apoptosis detection by the TUNEL method. The pancreata from Ins2WT/WTChop+/+, Ins2WT/C96YChop+/+, and Ins2WT/C96YChop–/– male mice were obtained and costained for insulin (red) and TUNEL-positive cells (green). Phase-contrast images and fluorescence images of the same fields are shown. Original magnification: ×200.
