[Histonet] Re: rabbit anti-FITC

From:"C.M. van der Loos"

   Hi Liz, Gayle and Andrea,

   We were quite annoyed here too about discontinuing rabbit anti-FITC by
   Dako's. After complaining about it Dako let me know that a HRP-labeled
   rabbit  anti-FITC  is still  available.  However,  that approach isn't
   sensitive enough  for my application below. I looked for a replacement
   and found   a   concentrated   rabbit  anti-FITC  from  BioGenesis no.
   4510-7804 ([1]www.biogenesis.co.uk). This   product still   needs   to
   be compared with the original Dako rabbit anti-FITC. When done, I will
   let you know my findings. The test will be a
   multistep enzymatic double  staining  procedure combining an unlabeled
   mouse primary with a FITC-labeled mouse primary antibody:
    1. unlabeled mouse primary 1
    2. polymer anti-mouse/HRP
    3. blocking step with normal mouse serum
    4. FITC-labeled mouse primary 2
    5. rabbit anti-FITC
    6. goat anti-rabbit/AP
    7. visualization of AP activity (Fast Blue BB or Vector Blue)
    8. visualization of HRP activity in red (AEC or Vector NovaRed)

   In this protocol a mouse anti-FITC obviously doesn't fit.

   This  is sad as this antibody worked so nicely.  It worked beautifully
   Rat antMouse CD4-FITC.  Chris van der Loos was the one who clued me in
   this  antibody, as he used it cleverly for his double staining.  Maybe
   has a new source for one of equal quality.
