An antigen-dependent negative selection blood cell separation method is described. Rare circulating epithelial cells can be separated from blood by depleting erythrocytes from a blood sample. Erythrocytes are depleted by agglutination. The new method comprises the use of an agglutinating agent, such as an anti-glycophorin A or glycophorin B antibody, as glycophorin A or B are present on erythrocytes and not on the desired epithelial cells. With regular mixing, desired rare circulating epithelial cells do not become entrapped in the red cell agglutinate.

Method for enriching rare cell subpopulations from blood

The invention describes quality control devices for assays that measure analytes in cells and tissue samples, and methods of use thereof. In particular, the quality control device comprises a matrix affixed with synthetic controls in different concentrations, or different synthetic controls. The quality control device can be adhered to a microscope slide via an adhesive or chemically attached to a microscope slide and processed simultaneously with a tissue sample.

Quality control for cytochemical assays

The invention describes a method for attaching biological molecules, such as proteins, nucleic acids, and carbohydrates to a glass surface. In particular, a covalent attachment method is described wherein a glass surface is first activated with a water-stable form of an isocyanate, termed a protected isocyanate. The protecting group of the isocyanate moiety is displaced by amines, hydroxyl, or carboxyl groups of biological molecules, leading to covalent attachment to the glass surface.
