[Histonet] Re: F4/80 mouse paraffins

[Reynolds,Donna M]

We have used rat anti-mouse F4/80 from Cell Sciences, clone BM8 on mouse FFPE tissue successful. We used a 1:50 dilution and Proteniase K (Dako) for antigen retrieval.  Our secondary was BioCare Medical's 4+ biotinylated detection system.  It did take a longer than normal development time in the DAB but labeling was very nice.  You could give this a try with your antibody. Good luck.
