A specific enzyme-linked immunosorbent assay for determination of bovine IgM: use in screening hybridoma cell lines

A highly specific enzyme-linked immunosorbent assay (ELISA) is described for determination of bovine IgM and use in screening IgM-secreting hybridoma cell lines. The advantages of this assay over the method of radioactive labelling of cells followed by immune precipitation, SDS-PAGE, fluorography and autofluorography are demonstrated.
