In the chicken bursa of Fabricius (BF), the interfollicular epithelium (IFE) consists of cylindrical- and cuboidal-shaped cells. Among the cylindrical-shaped epithelial cells, mucus-producing and caveolin-1 (Cav-1)-expressing cells can be distinguished. Occasionally, the cuboidal-shaped cells also express Cav-1, which suggests that

A method which allows the highly sensitive and simple immunodetection of antigen-antibody complexes on nitrocellulose papers has been developed. The method is a modification of the procedure known as the "Nadi reaction" (oxidative coupling of 1-naphthol and N,N'-dimethyl-p-phenylendiamine) for histochemical
