DIPHTHERIA TOXOID

Journal of the American Medical Association, 1934
The work here reported was done with diphtheria toxoid furnished by Dr. William H. Park, director of laboratories and research, of the department of health of New York. Its purposes were: To test the relative immunizing value of a given diphtheria toxoid, with and without the addition of alum. To find the optimum dosage as to the amount and number of

Alum-Precipitation of Diphtheria Toxoid (Improvement of Diphtheria Alum-Toxoid)

The Journal of Immunology, 1936
Summary Precipitation of diphtheria-toxoid by alum depends on the pH under which the precipitate is formed. Purified toxoid requires much less amounts of alum to be precipitated than the original toxoid. One-eighth by volume of 4 per cent solution of alum seems to be sufficient for toxoid purified with calcium-phosphate to precipitate ...

Purification and Adsorption of Diphtheria Toxoid

Nature, 1946
THE method for purification of diphtheria toxoid, which h s been used at the State Bacteriological Laboratory of Sweden since 1943, consists of two different procedures: the so-called iso-electric precipitation with trichloracetic acid of the crude toxoid and the aluminium precipitation of the partialy purified material. The method, described brj ny in

Ionic interfaces and diphtheria toxoid interactions

Protein Expression and Purification, 2004
We present here a systematic study on the purification of the diphtheria toxoid (Dtxd) produced at the Instituto Butantan, by adding only one step on the entire process of its production. Aliquots of 1.0 ml of Dtxd were added to an equal amount of Q-Sepharose previously equilibrated with 500 mM Tris, pH 5.0-9.0 (increments of 0.5 pH units).
