A Technique for Electrophoresis in Agar Gel

Behavior of the Serum proteins in starch-agar-gel electrophoresis

A method for the electrophoresis of colicines in agar gel.

The design, construction, and use of an apparatus for the electrophoresis of colicines in agar gel is described, as are some preliminary experiments with it. The possibilities of this method in typing strains of colicinogenic organisms and for the study of colicines are also discussed. In 1953, Ludford and Lederer, using a simple apparatus, demonstrated that substances known as colicines consis...

Agar-gel precipitin-inhibition technique for plague antibody determinations.

An application of the agar-gel precipitin-inhibition technique we described previously can be used to detect plague antibodies in human and animal sera after a series of plague vaccine inoculations or after exposure to Pasteurella pestis. Determination of the minimal reacting concentrations of the plague antigen and antibody reagents, methods for combining reagents, and length of incubation per...

Agar-gel precipitin-inhibition technique for histoplasmosis antibody determinations.

The agar-gel precipitin-inhibition technique has been modified to detect antibodies of Histoplasma capsulatum in sera from human clinical cases and experimental animals infected with this organism. By use of this modified technique, the histoplasmosis can be detected more consistently and reliably than with the direct agar-gel diffusion test, and titers are comparable to those attained by the c...
