Bhasin JL, Lapointe-Shaw L: Antigenic analysis if Pasteurella multocida (serotype 1) by crossed immunoelectrophoresis: characterization of whole cell associated antigens. Can J Microbiol. 1980 Dec;26(12):1392-402.
Crossed immunoelectrophoresis and other related quantitative immunoelectrophoresis techniques have been used to elucidate the antigenic complexity of a reference preparation of capsular extract, potassium thiocyanate extract, lipopolysaccharide, heat-stable antigens, and free endotoxin from Pasteurella multocida serotype 1. The reactions of these cellular fractions in crossed immunoelectrophoresis, with reference anti-whole cell immunoglobulins disclosed five antigens in the capsular extract, seven in the potassium thiocyanate extract, one to three in the lipopolysaccharide, three in the heat-stable antigens, and five in the free endotoxin. Comparison of these reference antigen-antibody systems, in crossed immunoelectrophoresis, with intermediate gel containing wither a reference anti-cell envelope or anticytoplasmic immunoglobulins not only revealed the presence of additional antigens but also gave insight into the probably cellular origins (i.e., cell surface, cell envelope, or cytoplasm) of various antigens unveiled by reference anti-whole cell immunoglobulins. Using the principle of tandem crossed immunoelectrophoresis and crossed-line immunoelectrophoresis the immunochemical relationships between the antigenic components of these reference antigen-antibody systems were established. |
