Hi Anna, Your subject line is F4/80 and you are asking for CD68. I thought they are different antibodies, but I may be wrong. We have never been able to find CD68 ab that works well of FFPE mouse tissues. Recently we had success with F4/80 Rat anti-mouse Clone: BM8 from BioLegend. It only worked with citric buffer pH6 100C 10min.
We also use Iba-1 as macrophage marker on mouse FFPE tissues. If anyone has good CD68 on FFPE mouse tissues please could you share your experiences? It will be of great help. Hope this helps.
