Immunohistochemical detection of HNF4α in the choroid plexus. Slices of human (A, B) and rat (C, D) choroid plexus probes were stained with polyclonal antibodies against HNF4α. Arrows indicate representative HNF4α positive cells (A, C). To confirm specificity of the immunohistochemical localization antibodies were preabsorbed with excess of antigens for HNF4α (B, D). Patient identification numbers were indicated respectively and patient characteristics are given in Table 5. Magnification ×400.
