I have a batch of antigens here that will make you sick as a beast for at least a day.
Antigens were considered by Ehrlich to be proteins or to be related to proteins.
In these antigens he could detect only fatty acids or salts of fatty acids.
These extracts were carefully processed and were used as antigens.
The kind of antibody and the manner of its action will differ with the different kinds of antigens used.
Antigens were diluted with 0.9 per cent phosphate-buffered saline solution.
Formolization of the antigens was necessary as a means of preventing denaturation of the proteins by enzymatic activity.
