General description

Monoclonal Anti-Human Fibroblast Surface Protein (mouse IgM isotype) is derived from the 1B10 hybridoma1 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with cultured human thymic fibroblasts. Human fibroblast surface protein is a fibroblast antigen that is expressed mainly on human synovial, foreskin and thymic fibroblasts and is absent on human epithelial cells and lymphocytes.


cultured human thymic fibroblasts


Monoclonal Anti-Fibroblast Surface Protein antibody produced in mouse has been used in:
• immunofluorescence
• flow cytometry
• immunohistochemistry
• immunoblotting

Target description

This fibroblast antigen has been demonstrated on human synovial, mammary, foreskin and thymic fibroblasts and in malignant fibrosarcoma tissue. The antigen is both cell membrane and lysosome associated.

Biochem/physiol Actions

Monoclonal Anti-Fibroblast Surface Protein antibody is also used to remove fibroblasts from human cultured cells by inhibiting fibroblasts adherence to the culture vessel or by cytotoxic effect in the presence of rabbit complement. In addition, apart from the functional significance of cells characteristics, the characterization of cell lines is important for correlation of cultures with tissue origin, identification of the lineage to which the cells belong or the precursor status of the cells. Monoclonal antibodies to fibroblast surface protein should provide a powerful tool for control of fibroblast growth in a variety of human cell culture systems, such as thymic epithelial (TE) cell cultures allowing the growth of highly enriched populations of the TE cells.

Analysis Note

Working dilution is at least 1:500 by complement-mediated microcytotoxicity assay.
