C-reactive protein (CRP) was isolated from the acute phase serum of dogs subjected to surgical stimulation. Its properties were characterized. Canine CRP was isolated by ion-exchange chromatography using DEAE-Sephacel and DEAE-Sephadex A-50 and affinity chromatography using protein A-Sepharose CL 4B in combination with agar-block electrophoresis.

The relationship between intensity of inflammatory stimulation and production of α(2)-macroglobulin (α2M) and α(1)-acid glycoprotein (AAG) in rats was investigated. Sprague-Dawley rats were injected with turpentine oil at doses of 0.05, 0.2 or 0.4 mL/rat. Serum levels of α2M, interleukin (IL)-6 and cytokine-induced neutrophil chemoattractant-1 (CINC-1) were(More)
This paper describes the avidity of IgG antibody used for preparation of latex sensitized with IgG antibody (IgG-sensitized latex) and the agglutinability of IgG-sensitized latex in slide reversed passive latex agglutination (RPLA). Using immunodiffusion techniques, it was found that anti-canine C-reactive protein (CRP) sera from four rabbits immunized with(More)
A method is described for preparing latex particles sensitized with IgG antibody (IgG-sensitized latex) applicable to the slide reversed passive agglutination (RPLA) test. Soap-free latex (latex) was sensitized with IgG which had been isolated from rabbit anti-bovine lactoferrin serum using protein A Sepharose CL 4B. Unadsorbed protein-binding sites on the(More)
A bovine colostral antibody against verotoxin (VT) 2 of Escherichia coli O157:H7 was administered orally to beagle dogs. The antibody remained in the dogs' small intestine for at least 2 h, whereas little serum antibody remained 1.5 h after administration. Furthermore, the antibody activity of secretory IgA did not change until 2 h after administration;(More)
A capillary reversed passive latex agglutination test (capillary RPLA) was developed which allows quantification of serum C-reactive protein (CRP) within approximately 15 min. The logarithmic regression line (calibration curve) obtained after measuring each CRP concentration three times in twofold dilutions of a standard canine serum containing 222 μg/ml of(More)
