[Histonet] F4/80 help

From:=?iso-8859-1?b?yW1pbGllIA==?= =?iso-8859-1?b?QulsYW5nZXI=?= Trudelle


I'm using F4/80 (Serotec) for IHC on frozen mouse spleen. I'm using biotinylated
anti-rat IgG from Vector and Vectastain ABC kit and DAB also from Vector . I
have try a lot of different protocols and incubation time with F4/80 and i
always obtain yellow granules around my positive cells and on my isotypic
negative control as well. Does any one know what these granules are and how to
block their coloration????
