Hi Rita and histonetters,

OK, here's the scoop on our C4d staining of renal biopsies:

Biogeneis C4d catalog #2222-8004
10" R.T. acetone fixation of 4um thick frozen renal biopsies, air dry.
Stain on the Ventana ES for 16" or the Ventana NexES for 32" at 1:600.
Use Ventana iview DAB detection, Ventana AB block (biotin block) and hematoxylin counterstain.

We are currently investigating the use of Ventana's Morphosave as a 2" pretreatment in order to clean up the stain a bit.  It helps on the unusually dirty tissues but does compromise the morphology a bit.  The jury is still out on this.

Martha,

We only do C4d on frozen renal biopsies  mainly because the clinicians want
their answer sooner rather than later.

Our lab has had inquiries about adding this antibody to our protocol for
transplant renal biopsies and I wanted to hear from labs that are currently
performing it.  All the protocols I have seen reference frozen tissue but we
were wondering if there is a way to do it on ffpe tissues.  Any and all help
will be greatly appreciated!
