Three monoclonal antibodies (MAbs) were generated from splenocytes of a
BALB/c mouse immunized with heat-killed Mycobacterium tuberculosis. All
three MAbs bound to surface epitopes of M. tuberculosis as shown by
whole-cell enzyme-linked immunosorbent assay (ELISA), indirect
immunofluorescence, and immunoelectron microscopy. One immunoglobulin M
(IgM) MAb bound to lipoarabinomannan, the second IgM MAb bound to
mycolyl-arabinogalactan-peptidoglycan complex, and the third MAb, an IgG3,
bound to a surface epitope of an uncertain nature. The MAbs demonstrated
different cross-reactivity patterns with other mycobacteria. Two of the
MAbs were used to develop a modified ELISA spot assay for the detection of
mycobacteria.
