ANTIIHUMAN RETINOL BINDING PROTEIN ANTIBODY SENSITIZED LATEX FOR MEASUREMENT OF HUMAN RETINOL BINDING PROTEIN AND SAID LATEX PARTICLE COMPOSITION

摘要

PURPOSE:To measure RBP with a very slight amount of sample by using anti- human retinol binding protein (anti-human RBP) antibody sensitized latex. CONSTITUTION:An anti-human RBP antibody sensitized latex for measurement of humam RBP contg. the latex particles (polystyrene latex, 0.01-10mum mean grain sizes, 0.9-1.4 specific gravity) carrying anti-human RBP antibodies on the surface is obtained. Also, the latex particle composition contg. the latex particles carrying anti-human RBP antibodies on the surface as well as stabilizers (glycine, amino acid such as sodium glutamate, and dextran, the amounts of amino acid and dextran are 1.2-4.0pts.wt. and 1.6-6.0pts.wt. respectively based on 1pt.wt. the latex particles) is obtained. The RBP in blood serum is measured by a microtitration method by using the above-mentioned latex or composition obtd. by the above- mentioned manner.
