Note	Protocol: Protocol for Immunohistochemistry on paraffin sections: 1) Deparaffinize slides in chloroform for 30min and rehydrate to distilled water 2) Antigen retrieval: microwave treatment (700W) for 15min in 300ml 0.01M citrate buffer pH 6.0. 3) Incubate slides for 15min in 200ml methanol/4.8ml 30%H2O2 4) Rinse slides 2x in distilled water and for 5min in TBS, pH 7.5 5) Block with normal swine serum (NSS, Jackson Immunoresearch #014-000-121) diluted 1:10 in Tris buffered saline pH 7.5, containing 0.1% bovine serum albumin (BSA, Calbiochem). Cover sections with NSS and incubate for 15min in a humid chamber at room temperature (RT). 6) Remove serum from sections (do not rinse) 7) Incubate with primary antibody diluted in TBS/0.1%BSA, pH 7.5 for 60min in a humid chamber at room temperature 8) Rinse sections in TBS, pH 7.5 for 5min, 2x 9) Incubate with secondary antibody (rabbit anti mouse IgG+IgM-biotin, Dako E 0464) 1:400 diluted in TBS/0.1%BSA, pH 7.5 for 30min in a moist chamber, room temperature. Preincubate now StreptABComplex /HRPO in TBS/0.1%BSA, pH 7.5! 10) Rinse sections in TBS, pH 7.5 for 5min, 2x 11) Incubate with StreptABComplex /HRPO (DAKO, K 0377) for 30min in a humid chamber at room temperature 12) Rinse sections in TBS, pH 7.5 for 5min, 2x 13) DAB-staining Prepare 3,3 - diaminobenzidintetrahydrochloride (DAB) according the manufacturers instructions (e.g. DAB tablets) and incubate slides for 1-15 min. Check color reaction to avoid overstaining. 14) Rinse sections in TBS, pH 7.5 for 5min, 2x 15) Counterstain in haematoxylin for 1min and rinse in cold tap water for 10min 16) Mount slides with coverslips
