A method and composition for fixing and stabilizing tissues, cells, and cell components such that the antigenic sites are preserved for a useful period of time. The fixative employs a formaldehyde donor that is non-toxic, non-flammable, and that stabilizes the cell with minimal damage to and alteration of the cell morphology. In particular, the cell antigenic sites are left intact so that studies with monoclonal antibodies may be conducted. The invention also discloses a method for developing a positive control for test reagents and for test instrumentation. |
