Ja. Garciasainz et al., CHARACTERIZATION AND DETOXIFICATION OF AN EASILY PREPARED ACELLULAR PERTUSSIS-VACCINE - ANTIGENIC ROLE OF THE A-PROTOMER OF PERTUSSIS TOXIN, Vaccine, 10(5), 1992, pp. 341-344
An acellular pertussis vaccine was prepared from pertussis vaccine con
centrates by eliminating the cells by centrifugation and subsequent ac
id precipitation. SDS-PAGE analysis indicated the presence of 17 clear
ly defined bands including the subunits of pertussis toxin. The acellu
lar preparation was detoxified with glutaraldehyde and lost its undesi
rable effects (leukocytosis-promoting activity, histamine-sensitizing
activity and decrease in weight gain) but retained a very good protect
ive activity (PD50 almost-equal-to 2-mu-g protein/mouse). Sera from mi
ce immunized with this preparation indicated an antibody response agai
nst the A protomer of pertussis toxin.
