Method for determining MIF content
View Patent ↗A diagnostic method for determining MIF protein content in a sample using a direct or an indirect detection technique and wherein MIF is a human MIF protein having a molecular weight of approximately 12.5 kDa.
1. A diagnostic method for determining the amount of macrophage migration inhibitory factor (MIF) protein in a sample, comprising:
(a) contacting an anti-MIF antibody to the sample; and
(b) determining the amount of MIF protein in the sample using an immunoassay, wherein the immunoassay is selected from the group consisting of ELISA, radioimmuno assay (RIA), immunoprecipitation, immunohistocytochemistry, and Western analysis, and wherein said MIF protein is the human MIF protein having a molecular weight of approximately 12.5 kDa which exhibits MIF biological activity, and wherein the anti-MIF antibody binds specifically to the MIF protein.
2. The diagnostic method of claim 1 , wherein the sample is selected from the group consisting of blood, serum, urine, lymph, saliva, tumor tissue, placental tissue, umbilical cord tissue, amniotic fluid, chorionic villi tissue and combinations thereof.
3. The diagnostic method of claim 1 , wherein the anti-MIF antibody is a monoclonal antibody or antigen-binding fragment or fusion protein thereof.
4. The diagnostic method of claim 1 , wherein the sample is from a patient that is known or suspected to be suffering from a condition or disease caused by cytokine-mediated toxicity.
5. The diagnostic method of claim 4 , wherein said condition or disease caused by cytokine-mediated toxicity is selected from the group consisting of endotoxin-induced septic shock, endotoxin-induced toxic shock, shock, inflammatory diseases, graft versus host disease, autoimmune diseases, acute respiratory distress syndrome, granulomatous diseases, chronic infections, transplant rejection, cachexia, asthma, viral infections, parasitic infections, malaria, and bacterial infections.
6. The diagnostic method of claim 1 , wherein the sample is a member selected from the group consisting of body fluid, tissue and cell lysate.
7. A method for determining an amount of macrophage migration inhibitory factor (MIF) protein in a sample, comprising:
(a) contacting an anti-MIF antibody to the sample; and
(b) determining the amount of MIF protein in the sample using a direct or an indirect detection technique and wherein the MIF protein is human MIF, having a molecular weight of approximately 12.5 kDa, containing the amino acid sequence of SEQ ID NO: 5 and which exhibits MIF biological activity.
8. The diagnostic method of claim 7 , wherein the direct or indirect detection technique involves an immunoassay.
9. The diagnostic method of claim 7 , wherein the sample is selected from the group consisting of blood, serum, urine, lymph, saliva, tumor tissue, placental tissue, umbilical cord tissue, amniotic fluid, chorionic villi tissue and combinations thereof.
10. The diagnostic method of claim 7 , wherein the sample is a member selected from the group consisting of body fluid, tissue and cell lysate.
