Abstract
An apparatus is provided for determining binding of mammalian cells to carbohydrates on a chromatographic plate surface. The chromatogram is performed, the plate introduced into a cell adhesion chamber, and the chamber filled with an appropriate cell containing medium. After mild centrifugation to ensure cell carbohydrates interaction, non-specific adherent cells are removed by gravitational force in the opposite direction. The plate is then carefully washed without subjecting the plate to any air/liquid interface, the cells fixed and the plate analyzed.
