Three MAb M2, B6, P1 (IgG1 type) against human urinary trypsin inhibitor (UTI), a glycoprotein with antiinflammatory properties, have been produced by hybridization of mouse myeloma cells P3o1 with spleen cells of immunized mice BALB/c. Competitive ELISA-examination of peroxidase conjugates of M2, B6, and P1 MAb in the presence of the trypsin binding domain shows the highest affinity of M2 antibody for this domain. On the basis of MAb M2 competitive ELISA of UTI concentration in urine is proposed. ELISA detectable changes in the UTI content of urine from patients with nephritis without renal failure can be considered as an early index of renal parenchyma damage.

UI MeSH Term Description Entries
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D008297 Male Males
D008807 Mice, Inbred BALB C An inbred strain of mouse that is widely used in IMMUNOLOGY studies and cancer research. BALB C Mice, Inbred,BALB C Mouse, Inbred,Inbred BALB C Mice,Inbred BALB C Mouse,Mice, BALB C,Mouse, BALB C,Mouse, Inbred BALB C,BALB C Mice,BALB C Mouse
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
