[Histonet] RE: CD4 1F6 clone (Steven Weston)

We use this clone for rhesus macaques FFPE and it works. Not the best but still works.
We do 1:20 dilution,  60' incubation, high pH 9.0 HIER (BondRX or Biocare chamber), and H2O2 block before protein block.
We know it works better on frozen than on FFPE.

I hope this helps.

I also tried it without H2O2 with no result either.
Anyone else had these problems with this clone ???
Interestingly in the past I used the duo pack of CD4/8 that had the 1F6 for cd4 and the 4B11 clone of cd8 and they both worked.
May have to try the 4b12 clone for cd4.

Hi Histonetters
Has anyone else had difficulty getting  this clone to work? cd4 1F6 from leica microsystems (formerly novocastra).
I've tried just about every trick in my book and still no staining.
Particularly i made sure i did the peroxidase block prior to HIER (i even tried using it after the primary) and have tried low, high and middle pH buffers with antibody concentrations from 1/10-1/40 for 60 and 90 mins and use envision plus detection with DAB plus. I've had two batches of this over the last ten years and neither has worked.
Anyone else with the same experience ?
