Preparation of polyclonal antibodies to diminazene and its detection in animal blood plasma.

This work was undertaken to examine the possibility of preparing polyclonal antibodies to diminazene by using colloidal gold nanoparticles as an antigen carrier and adjuvant. The antibodies prepared by us were used for immunodot determination of diminazene in calf-blood plasma. The immunochemical results agreed with those obtained by high-performance liquid chromatographic estimation of diminazene content in animal biological fluids.

Obtainment of polyclonal antibodies to clenbuterol with the use of colloidal gold.

The effectiveness of an in vivo synthesis of antibodies to clenbuterol with the use of gold nanoparticles as a carrier was evaluated. For comparison, conjugates of clenbuterol with bovine serum albumin were used in immunization. The serum titer was determined by an ELISA.

The effectivity analysis of accumulation of liposomal, micellar, and water-soluble forms of diminazene in cells and in organs.

The study was aimed at evaluating the effectiveness of liposomal, micellar, and water-soluble drug forms of diminazene for its localization in cells and selective accumulation at the sites of aggregation of pathogenic organisms. Pharmacological and dynamic properties of a new injection micellar diminazene preparation were experimentally determined. These properties were compared with the same parameters obtained for the water-soluble and liposomal diminazene aceturate drug forms.
