Anne, How long do you leave your tissue in the fixative? If you have a protocol you are willing to share it would be most appreciated.
Thanks!!

Also, make sure that your tissue processor has no trace of formalin in the lines or in the first alcohols during processing. -Anne From: ih...@googlegroups.com<mailto:ih...@googlegroups.com> [mailto:ih...@googlegroups.com] On Behalf Of pru...@ihctech.net<mailto:pru...@ihctech.net> Sent: Thursday, February 14, 2013 4:01 PM To: ih...@googlegroups.com<mailto:ih...@googlegroups.com>; histonet@lists.utsouthwestern.edu<mailto:histonet@lists.utsouthwestern.edu> Subject: FW: [IHCRG] CD8 on mouse tissue Here is the reference for zinc salt fixed mouse tissue labeled for cd4/8 PE, it looks really promising.

CD4 and CD8 on murine tissue does not like formalin fixation and paraffin processing, which is why the golden standard for those two is snap frozen murine tissue acetone/ethanol fixed.

However, there is some interesting data out there using a zinc fixative or PLP. While Frozen sections will work for the IHC they may be limiting in terms of the image analysis due to thicker sections and decreased morphological preservation. I will lay out my data for you to poke holes in it. So did you ever do much in the way of CD8 localization on murine tissue? AJ <image001.png> A.J.
