Monoclonal antibodies (Mo-Abs) were prepared by fusing mouse myeloma cells (PAI) with spleen cells of mice immunized with Tamm-Horsfall glycoprotein (THGP). Six Mo-Abs screened for the presence of anti-THGP antibodies by enzyme linked immunosorbent assay and by immunoblotting assay have been produced. The specificity studies clearly indicated that the Mo-Ab individualized four distinct epitopes. The immunofluorescent reaction by the Mo-Abs have been analyzed in the human kidney section with normal or a minimal change. The No. 1, 2, 3 and 5 of Mo-Abs reacted with the cytoplasm of distal convoluted renal tubules, while the No. 4 and 6 of Mo-Abs reacted with a substance in the capsular space as well as with the cytoplasm of distal convoluted tubules. The sites of synthesis of this substance, detected in the capsular space by No. 4 and 6 of Mo-Abs and held the immunological cross-reactivity with tubular THGP, is presently uncertain. The specificity of the Mo-Ab may be of considerable value for further studies.

D009088	Mucoproteins	Conjugated proteins in which mucopolysaccharides are combined with proteins. The mucopolysaccharide moiety is the predominant group with the protein making up only a small percentage of the total weight.
D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children
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.

D006825	Hybridomas	Cells artificially created by fusion of activated lymphocytes with neoplastic cells. The resulting hybrid cells are cloned and produce pure MONOCLONAL ANTIBODIES or T-cell products, identical to those produced by the immunologically competent parent cell.	Hybridoma
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
