ABSTRACT:
Yeast cells are converted into carrier particles useful as carriers for proteins and other materials useful in agglutination tests by cross-linking the proteins of the cell cytoplasm followed by stabilization of the carbohydrates of the cell wall by reaction with an epoxide. The stabilized cells obtained may be dyed and may be esterified or etherified to block the hydroxyl groups in their surfaces. They may be coupled to the protein or other material by activation, e.g. with cyanuric chloride, followed by reaction with the protein or other material to produce diagnostic agents useful in test kits.
