Summary Precipitating antibodies against group A Candida albicans mannan were demonstrated in sera from healthy volunteers and from patients with mucocutaneous isolates of Candida. Forty-eight per cent of sera from healthy volunteers and 69% of sera from patients with mucocutaneous isolates of Candida had precipitating antibodies when ...

Precipitin-Production in Chickens
The Journal of Immunology, 1946Summary The in vitro rise in the precipitin titer was studied in chickens injected with mammalian serum. Rise in titer started as early as 11 hours after bleeding and in the majority of cases the peak was reached at 5 to 8 days. The rise in titer varies but the titers secured within 24 hours were not indicative of the final titers that ...

Rapid Double Diffusion Precipitin Analysis
The Journal of Immunology, 1954Summary A modification of the Ouchterlony three-depot method of double diffusion precipitin analysis is described. The use of depots which form long straight interfaces with the reaction arena leads to the development of rectilinear zones of precipitate.

Reversed electroimmunodiffusion for quantitating precipitins
Journal of Immunological Methods, 1974Abstract This paper describes a new technique, reversed one-dimensional single electroimmunodiffusion (REID), for rapid and simple quantitation of antiserum precipitins on a continouous scale, reports results of experiments on factors affecting use and interpretation of this new method, and describes a new device for accurately and simply metering ...

Slide Gel Diffusion Precipitin Test
Nature, 1958A MODIFICATION of the plate gel diffusion test1 is proposed, carried out on microscope slides. The use of a thin layer of media on the slide, together with a reduction in the distance between antigen and antibody basins, resulted in an earlier appearance of the reaction.

Precipitin Production in Chickens
The Journal of Immunology, 1952Summary The similarity of pheasant and owl antibeef-albumin precipitins to chicken precipitins was demonstrated. At low salinity, about 1%, precipitation of these antibodies was very incomplete; on increasing the salinity the precipitation became more complete.

Journal of the American Medical Association, 1926
Important as previous studies on hemolytic streptococci as a cause of scarlet fever may be, especially immunologic studies, convincing proof of etiologic relationship of hemolytic streptococci to scarlet fever was lacking until the Dicks produced the disease in human volunteers with pure cultures of this organism.

Precipitin Production in Chickens
The Journal of Immunology, 1950Summary Splenectomy reduces the ability of chickens to produce precipitating antibodies. Splenectomized chickens are less responsive to small injections of antigen than unoperated animals.

Electrophoretic Precipitin Test on Cellulose Acetate
American Journal of Clinical Pathology, 1966The simultaneous electrophoretic movement of antigen through antiserum on paper, termed transmigration, is a means of detecting immune reactions. In order to detect multiple precipitin reactions rapidly as a means of demonstrating antigen homogeneity or heterogeneity, antiserum may be separated electrophoretically on cellulose acetate, immediately ...

PRECIPITIN TESTS FOR AUTO‐IMMUNIZING THYROIDITIS
Australasian Annals of Medicine, 1960SummaryThe results of precipitin and flocculation tests on the serum of 76 patients with thyroid disease are presented and discussed. A positive precipitin reaction to thyroid extract indicates that, at one time or other, the patient has become sensitized to thyroglobulin.A thyroid precipitin test employing normal electrophoretic equipment is described.
