Identification of Crude and Purified Bacterial Proteinases by Agar Gel Diffusion and Agar Gel Electrophoretic Procedures

Arbovirus identification by an agar-gel diffusion technique.

A double diffusion-in-agar test was used to investigate precipitation reactions of 75 arboviruses. Specific reactions were regularly observed with members of arbovirus groups B, California, Simbu, Turlock, Hart Park, vesicular stomatitis, and several other arboviruses as well as with a member of the Tacaribe group and a herpesvirus. The results demonstrated the feasibility of applying this tech...

Comparison of ELISA and Agar Gel Diffusion Techniques in Diagnosis of Human Hydatidosis.

Identification of Actinomyces israelii and Actinomyces naeslundii by fluorescent-antibody and agar-gel diffusion techniques.

This study was an attempt to develop a fluorescent-antibody (FA) test to differentiate Actinomyces israelii and A. naeslundii as an aid in their laboratory identification. Two strains of A. israelii (X522 and A601) and two strains of A. naeslundii (X454 and X600), which had received intensive study by several investigators, were used for the immunization of rabbits. Working titers, based on tes...
