Immunohistochemistical detection of MHC Class II using antibody ab23990 on PFA-fixed rat spleen tissue sections. Antibody diluted at 1/100 and incubated for2 hours in TBS/BSA/Tween/azide. Secondary antibody: anti mouse IgG conjugated to biotin (1/100). After dissection of spleen from PFA-perfused specimen it was sampled and further immersion-fixed for two Hrs. After subsequent immersion in 30% Sucrose, specimens were snap-frozen. Before immunostaining, the 8 micron sections were placed in a 60 degree C oven for 60 mins to enhance adhesion. The submitted image shows white pulp (PALS) and a small area of red pulp (RP-upper left). The Periarteriolar Sheath (PALS) with it's Central Arteriole/artery (CA)shows many positive cells (B-lymphocytes and Macrophages) and negative lymphocytes (T-cells?). The Marginal Sinus (MS) is clearly seen between the PALS and the Marginal Zone (MZ). There is a clear Germinal Centre (GS) in this image. Lymphoid tissue is not my speciality so I apologise for any inaccuracies.

ab23990 staining MHC Class II in Rat spleen tissue by Immunohistochemistry (Frozen sections). The sections were fixed in PFA prior to blocking with 10% serum for 20 minutes at 24ºC. The primary antibody was diluted 1/100 in PBS and incubated with the sample for 16 hours at 4ºC. An Alexa Fluor® 488-conjugated donkey anti-mouse polyclonal was used as the secondary antibody, diluted 1/1000 for 1 hour at room temperature. Counterstained with Hoechst 33258 (blue) for 10 minutes at room temperature
