Scientific Data Images for Human/Mouse/Rat MIF Antibody

Detection of Human MIF antibody by Western Blot.

Detection of Human MIF by Western Blot.

Western blot shows lysates of THP-1 human acute monocytic leukemia cell line and U937 human histiocytic lymphoma cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse/Rat MIF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-289-PB) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF017). 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 Mouse and Rat MIF antibody by Western Blot.

Detection of Mouse and Rat MIF by Western Blot.

Western blot shows lysates of J774A.1 mouse reticulum cell sarcoma macrophage cell line and NR8383 rat alveolar macrophage cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse/Rat MIF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-289-PB) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF017). A specific band was detected for MIF at approximately 12-14 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human MIF by Simple WesternTM.

Simple Western lane view shows lysates of THP-1 human acute monocytic leukemia cell line, loaded at 0.2 mg/mL. A specific band was detected for MIF at approximately 12 kDa (as indicated) using 10 µg/mL of Goat Anti-Human/Mouse/Rat MIF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-289-PB) . This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: MIF

MIF (or macrophage migration inhibitory factor) was the first lymphokine/cytokine to be recognized in the pregenomics era (1, 2). Regardless, it is one of the least understood of all inflammatory mediators (1, 3). Human MIF is a 12.5 kDa, 115 amino acid (aa) nonglycosylated polypeptide that is synthesized without a signal sequence (4-7). Secretion occurs non-classically via an ABCA1 transporter (8). The initiating Met is removed, leaving Pro as the first amino acid. The molecule consists of two alpha-helices and six beta-strands, four of which form a beta-sheet. The two remaining beta-strands interact with other MIF molecules, creating a trimer (2, 9, 10). Structure-function studies suggest MIF is bifunctional with segregated topology. The N- and C-termini mediate enzyme activity (in theory). Phenylpyruvate tautomerase activity (enol-to-keto) has been demonstrated and is dependent upon Pro at position #1 (11). Amino acids 50-65 have also been suggested to contain thiol-protein oxidoreductase activity (12). MIF has proinflammatory cytokine activity centered around aa’s 49-65. On fibroblasts, MIF induces, IL-1, IL-8, and MMP expression; on macrophages, MIF stimulates NO production and TNF-alpha release following IFN-gamma activation (13, 14). MIF apparently acts through CD74 and CD44, likely in some form of trimeric interaction (15, 16). Human MIF is active on mouse cells (14). Human MIF is 90%, 94%, 95%, and 90% aa identical to mouse, bovine, porcine, and rat MIF, respectively.
