[Histonet] Control tissue for skin DIF

[Luke A Perkocha]

   Hello,
   I  am trying to develop a protocol for doing direct immunofluorescence
   testing  on  skin  for  bullous  disease.  I  have  a couple of sample
   protocols  but  none  say  anything about positive control tissue. I'm
   uncomfortable running the test on clinical specimens and reporting out
   a  negative,  without  good  positive  controls. Does anyone know of a
   commercial  source  for  positive  control tissue, or does anyone have
   some  they  would  be  willing  to  share  for  development? Help much
   appreciated.
   Thanks,
   Luke
