Detection of Mouse MIF by Western Blot. Western blot shows lysates of J774A.1 mouse reticulum cell sarcoma macrophage cell line. PVDF membrane was probed with 1 µg/mL of Rat Anti-Mouse/Rat MIF Monoclonal Antibody (Catalog # MAB19781) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for MIF at approximately 12 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of MIF in J774A.1 Mouse Cell Line by Flow Cytometry. J774A.1 mouse reticulum cell sarcoma macrophage cell line was stained with Rat Anti-Mouse/Rat MIF Monoclonal Antibody (Catalog # MAB19781, filled histogram) or rat IgM isotype control antibody, followed by Allophycocyanin-conjugated anti-rat IgM. To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Background: MIF
MIF (Macrophage Inhibitory Factor; also GIF) is a 12-13 kDa member of the MIF family of proteins. Although secreted, it possesses no definitive signal sequence. MIF is widely expressed and serves to regulate immune reactions. On macrophages and B cells, MIF binds to a CD74:CD44 complex, initiating downstream signaling. On monocytes, this promotes TNF alpha production plus IFN-gamma -stimulated NO production. On B cells, this promotes B cell survival. MIF also binds to leukocyte CD74:CXCR2 and CD74:CXCR4 heterodimers, initiating T cell and monocyte migration. A tautomerase activity has also been shown for MIF and is suggested to involve the entire length of the molecule. Mouse MIF is 114 amino acids (aa) in length. MIF is phosphorylated at Ser91, and an additional, singular Cys residue is covalently linked to MIF at Cys60. MIF is considered to act as a homotrimer. Full-length mouse MIF shows 90% and 99% aa sequence identity with human and rat MIF, respectively.
