Background: CD68  is a marker predominantly expressed on monocytes and macrophages and is used to identify tumor-associated macrophages (TAMs). Macrophages home to specific targets in part through the interaction between CD68 and tissue- and organ-specific lectins or selectins. CD68 staining can be combined with HLA-DR to identify M1 macrophages or with CD163 to identify M2 macrophages, macrophage phenotypes with prognostic associations to outcomes in certain cancers.

Validation: Each lot of conjugated CD68 antibody is quality control tested by MIBIscope™ analysis of stained tissue microarray using the appropriate positive and negative tissue field of views and are pathologist verified.

Recommended Usage: 1 uL of CD68 antibody per 100 uL staining volume using the MIBI™ Staining Protocol.
For optimal results, antibody should be titrated for each desired application.  Suggested starting range is 1:100.
