Article having an organic dye and a monolayer of dried mammalian cells and a method for utilizing the article

摘要: A method for drying mammalian cells, such as erythrocytes, lymphocytes, leukocytes and platelets onto a solid-phase support use in immunoassays through of solution an article prepared by method. The comprises immobilizing monolayer cells the non-covalent binding. This is accomplished staining with organic dye having net positive charge which permits binding carry negative to support. These are dried or fixed addition aqueous monosaccharide, disaccharide, trisaccharide cyclitol salt. preferred monosaccharide D-(-)glucose salt sodium chloride. 1.0 M dextrose 154 mM contacted immobilized immediately decanted any excess water removed sealed pouch dessicant material 3-8 days at between 2°-8° C. amount time required complete 7
