Barbituric acid antigens are prepared by coupling 5- or 5,5-substituted barbituric acid to immunogenic carrier materials. In preferred embodiments, proteins are used as the carrier materials and the coupling is effected by an amide linkage between the 5-substituent of the barbituric acid and a carboxyl or amino group of the protein. The resulting antigens produce immunological effects when injected into host animals, including the formation of antibodies specific for 5- and 5,5-substituted barbituric acids. These specific antibodies are useful in bioanalytical techniques for the assay of barbituric acids in biological fluids.
巴比妥酸抗原是通过将5-或5,5-取代的
巴比妥酸与免疫原性载体材料偶联制备而成。在优选实施例中,蛋白质被用作载体材料,并且通过
巴比妥酸的5-取代基与蛋白质的羧基或
氨基之间的酰胺键进行偶联。注射这些抗原到宿主动物体内会产生免疫效应,包括产生特异性针对5-和5,5-取代的
巴比妥酸的
抗体。这些特异性
抗体在
生物流体中测定
巴比妥酸的
生物分析技术中很有用。
