Figure 2 HLA-C protein expression levels in total protein extracts from psoriasis, eczema and normal skin biopsies. (a) Box plot representation of HLA-C expression according to sample group, measured by densitometry on Western blot analysis. (b) Box plot representation of HLA class I expression, measured by densitometry on Western blot analysis and detected by β2-microglobulin staining. LE=lesional eczema, LG=lesional guttate psoriasis, LP=lesional plaque psoriasis, N=normal, NLE=non-lesional eczema, NLG=non-lesional guttate psoriasis, NLP=non-lesional plaque psoriasis.
