we show that formaldehyde fixation of salmonella typhimurium lipopolysaccharide ( lps ) to ribosomes purified from brucella abortus induced a primary immunoglobulin m ( igm ) response to lps in c3h/hej mice and upon revaccination resulted in elevated titers of igm and induction of igg antibody to the o antigens of lps , as measured by an enzyme-linked immunosorbent assay .
