Isolation of specific and common antibodies to staphylococcal enterotoxins A and E by affinity chromatography.
Specific and common antibodies to staphylococcal enterotoxins A and E (SEA and SEE) were isolated from anti-SEA and anti-SEE antisera by affinity chromatography. Anti-SEA and anti-SEE antisera were passed through a column with the cross-reacting enterotoxin coupled to a CNBr-activated Sepharose 4B matrix. Specifically bound common antibodies were eluted with NaSCN. The isolated specific antibod...
متن کاملSpecificity and cross-reactivity of staphylococcal enterotoxin A monoclonal antibodies with enterotoxins B, C1, D, and E.
The cross-reactivity of monoclonal antibodies produced against staphylococcal enterotoxin A with purified and crude enterotoxins B, C1, D, and E and the specificity of such reactions were evaluated by the indirect enzyme-linked immunosorbent assay and immunoblotting of Western blots (from sodium dodecyl sulfate-polyacrylamide gel electrophoresis) followed by autoradiography. Purified and crude ...
متن کاملImmunologic cross-reactivity of type A streptococcal exotoxin (erythrogenic toxin) and staphylococcal enterotoxins B and C1.
Immunologic cross-reactivity between Streptococcus pyogenes type A exotoxin (erythrogenic toxin) and Staphylococcus aureus enterotoxins B and C1 was demonstrated by Ouchterlony double diffusion, Western immunoblot, and immunodot analyses. Specific antiserum to type A streptococcal exotoxin reacted more strongly with staphylococcal enterotoxin B than with enterotoxin C1. The reactivity of type A...
متن کاملChromatofocusing: a new method for purification of staphylococcal enterotoxins B and C1.
A new chromatographic procedure was developed which obtained highly purified preparations of staphylococcal enterotoxins B and C1 in yields of 60% from cultures of Staphylococcus aureus and which is faster than any of the separation methods used previously. The procedure involves chromatography on carboxymethylcellulose, removal of alpha-toxin by adsorption to rabbit erythrocyte membranes, and ...
متن کاملPyrogenic responses to staphylococcal enterotoxins A and B in cats.
Pyrogenic responses, ranging up to 4.8 F, were induced in cats by oral administration of highly purified staphylococcal enterotoxin B in doses from 10 to 100 mug/kg. Fever was a more sensitive indicator of intoxication than was emesis. Highly purified preparations of enterotoxin A, whether administered intravenously (0.01 to 1.0 mug/kg), orally (10 to 25 mug/kg), or into the cerebral ventricles...
