Hi to All!  I am currently in a dilemna as I am trying to stain xenograft
tissue for mouse and rat CD45 positive cells.  Does anyone know of a polyclonal
rabbit or goat anti rat or anti mouse CD45???  This would greatly improve our
ability to confirm which cells are rat derived and which cells are mouse derived
without the issue of x-reactivity which is currently a problem. I have consulted
the Linscott Directory but with limited success.  Any suggestions would be very
much appreciated!  Thank you in advance!
