Abstract

A simple three-layer sandwich enzyme-linked immunoadsorbent assay (sandwich-ELISA) has been developed for murine macrophage colony-stimulating factor-1 (CSF-1) using the two monoclonal antibodies on which we recently reported (J. Immunol. (1988) 141, 483). The anti-CSF-1 monoclonal antibodies used in this assay recognize different epitopes of the same antigen, thereby permitting the detection of low amounts of CSF-1. This assay is specific to murine CSF-1. Recombinant human macrophage colony-stimulating factor, murine GM-CSF, or IL-3, either alone or together with CSF-1, does not interfere with the assay. The advantage of this assay over other reported immunoassays for CSF-1 is that radiolabeled or large quantities of purified CSF-1 are not required. This sandwich-ELISA compares favorbly with other assays in its rapidity, simplicity, and sensitivity.
