Melanie,
  We have had very good luck with CD5.  I hope we are both talking about
human tissue, by the by.  CD5  clone 4C7,  from Novocastra (Australian

We pretreat in citrate buffer in a microwave pressure cooker for 10
minutes at pressure, and run it at 1:25 using an ABC detection system and
DAB chromogen.

  Cyclin D1 has been trickier, and doesn't look as nice, but this is our
best so far:
cyclinD1, clone DR1BC2, Biocare Medical  (I don't have Australian info,
but USA info is Phone:  800-799-9499, 888-531-8287  Fax:  925-944-7888)
  We pretreat in a vegetable steamer for 40 minutes in (preheated) pH 10
Tris buffer.  We run it at 1:25 using an ABC detection system and DAB
chromogen.

Good Luck,
