Figure 5From: The E5 protein of the human papillomavirus type 16 down-regulates HLA-I surface expression in calnexin-expressing but not in calnexin-deficient cellsCo-localization of HPV16 E5 with calnexin. HaCaT cells were transfected with AU1- tagged codon-optimised E5 or pEGFP-E5 and analysed after 24 h by confocal laser scanning microscopy using a monoclonal anti-AU1 and/or polyclonal anti-calnexin Abs.Back to article page
