<p>Compositions for inhibiting nonspecific binding protein to water insoluble surfaces, where specific binding of protein is involved. Specifically, hydrophilic polysaccharides, normally soluble in water, are covalently bonded to the water insoluble surface to substantially completely coat the surtace. A biological substance may then be coupled to the polysaccharide and permit specific binding of protein to the covalently bonded biological substance and easy removal of nonspecifically bound protein. The compositions find use in competitive protein binding assays, cytology, serology, agglutination assays and the like.</p> |
