[Histonet] immunofluorescent antibody tissue controls

[LINDA MARGRAF]

Dear Histonetters
We are continually running low on control tissue for our
immunofluorescent (IF) stains for IgG, IgA, IgM, and C3 that we run on
kidney biopsies.  Our pediatric population rarely has a kidney removed
for diseases with antibody deposits and none of our neighboring
hospitals has any control tissue to spare. DOes anyone know of a good
commercial source for positive IF control tissue for Igs and C3?
Thanks
