Latex agglutination-inhibition test for opiates compared with other immunochemical techniques.

Rapid latex agglutination inhibition reaction test for morphine in urine

A simple and rapid immunoassay of morphine based on latex agglutination inhibition reaction has been developed. Morphine-6-succinate is a morphine derivative, and its bovine serum albumin (BSA) conjugates were synthesized and characterized. The hapten density in the conjugate was determined spectroscopically to be 8.2 mol per mol of BSA. It was found that morphine-6-succinyl-BSA (M-6-S-BSA) exh...

A latex agglutination test for lectin binding.

Blood group A + H substance purified from hog gastric mucin was fixed to polystyrene particles by physical absorption to produce a lectin-agglutinable latex. Agglutination of this latex by soybean agglutinin, concanavalin A, and wheat germ agglutinin is specifically inhibited by the respective monosaccharide haptens and is not affected by known noninhibitory sugars. The sensitivity of the assay...

Rapid latex agglutination test for extraluminal amoebiasis.

AIMS To develop a rapid latex agglutination screening test for invasive amoebiasis. METHODS The performance of an in-house latex agglutination test was compared with three standard serological techniques--the immunofluorescent antibody test (IFAT), the indirect haemagglutination test (IHA), and the cellulose acetate precipitin (CAP) test. Forty six sera were screened; 12 from negative control...

Rapid latex agglutination test for rubella antibody.

The latex agglutination card test (Rubascan) for the detection of rubella antibody was compared with the standard hemagglutination inhibition and enzyme-linked immunosorbent assay tests. There was complete agreement with sera which had hemagglutination inhibition titers of >/=16. Sera with low levels of antibody which were positive in the enzyme-linked immunosorbent assay, however, gave negativ...
