Description of Target CD68 is considered a pan macrophage marker, predominantly expressed on the intracellular lysosomes of tissue macrophages/monocytes, including Kupffer cells, microglia, histiocytes and osteoclasts, and is expressed to a lesser extent by dendritic cells and peripheral blood granulocytes. CD68 is expressed by many tumor types including some B cell lymphomas, blastic NK lymphomas, melanomas, granulocytic (myeloid) sarcomas, hairy cell leukemias, and renal, urinary and pancreatic tumors, and can be used in cancer studies to demonstrate the presence/localization of macrophages.
Rat anti mouse CD68 antibody, clone FA-11, has been used in many mouse models for the identification of CD68 in immunohistochemical studies, using both frozen and paraffin-embedded tissues (Masaki et al. 2003) and (Devey et al. 2009).
Rat anti mouse CD68 antibody, clone FA-11 can be used in flow cytometry to detect intracellular CD68, following permeabilization, and can detect surface macrosialin at low levels in resident mouse peritoneal macrophages which can be enhanced with thioglycollate stimulation.

Species: Saposin C-deficient mice
Experiment Name: Histological studies
Experiment Background: The structure of saposin C is restrained by three disulfide bonds. Biophysical studies have shown that saposin C has membrane fusion properties. This fusogenic property is thought to be involved in the maturation of multivesicular bodies. Dissection of the saposin C peptide and in vitro and in vivo studies indicate regional localization of these multiple functions to specific regions of the protein, including neuritogenic activity and GCase activation. The fusogenic and neuritogenic activities localize to the 40 amino acids of the N-terminal, whereas the COOH-half contains the GCase activation domain. The former functions can be duplicated with the appropriate saposin C peptide fragments. In comparison, activation of GCase requires the COOH-half within a ‘saposin’ structure with intact disulfide bonds. The N-terminal 35–40 amino acid sequence is not critical to this GCase activation function, as the corresponding peptide sequence from saposin B can fulfill the overall requirements.
Experimental Steps: Following CO2 narcosis, mice were perfused with saline and then 4% paraformaldehyde.2.The tissues were dissected and fixed in 10% formalin, embedded in paraffin, sectioned and stained with hemotoxilin and eosin (H&E). 1. Paraffin sections of cerebellum were stained with mouse anti-calbindin D28K and mouse anti-GFAP. The antibodies were diluted in PBS. 2. Detection was done with ABC Vectastain and the alkaline phosphatase kit II (Black). 3. The slides were counterstained with methyl green. 4. For immunofluorescence staining, frozen sections from paraformaldhyde fixed tissues were incubated with mouse anti-GFAP. 5. Paraffin sections were reacted with mouse anti-NeuN. 6. The antibodies were diluted in PBS7.. Both biotinylated goat anti-mouse and streptavidin-conjugated fluorescent 480 (green) were applied to the sections. The samples were counterstained with antifade/DAPI. 8. The signals were visualized with a Zeiss Axiovert 200M microscope equipped with an Apotome. CD68 monoclonal antibody (FA-11) staining on the frozen sections was done.9. Karnovsky's fixative was used for ultrastructural studies.
