The Immunochemistry of Toxins and Toxoids
Methods for the purification and crystallization of tetanal toxin are described. The methods consist of the multiphase fractionation system involving methanol as the organic precipitating agent under controlled conditions of pH, ionic strength, protein concentration, and temperature. Crystalline tetanal toxin has an electrophoretic mobility of 2.8 x 10(-5) in veronal buffer of 0.1 ionic strengt...
متن کاملMass Spectrometric Analysis of Multiple Pertussis Toxins and Toxoids
Bordetella pertussis (Bp) is the causative agent of pertussis, a vaccine preventable disease occurring primarily in children. In recent years, there has been increased reporting of pertussis. Current pertussis vaccines are acellular and consist of Bp proteins including the major virulence factor pertussis toxin (Ptx), a 5-subunit exotoxin. Variation in Ptx subunit amino acid (AA) sequence could...
متن کاملThe diphtheria and pertussis components of diphtheria-tetanus toxoids-pertussis vaccine should be genetically inactivated mutant toxins.
Replacement of cellular with acellular pertussis (aP) vaccines has considerably reduced the systemic reactions observed with diphtheria-tetanus toxoids-pertussis vaccine but has not eliminated the extensive swelling (sometimes involving an entire limb) observed after the fifth injection of diphtheria-tetanus toxoids-aP (DTaP) vaccine. This local reaction, which is likely an Arthus hypersensitiv...
