Document Type and Number:
Japanese Patent JPH09500723
Kind Code:
A
Abstract:
The invention describes the preparation of preserved, non-infectious control cells. The control cells are prepared by modification, activation or otherwise changing selected normal leukocyte cells, tissue culture cells or zenogenic transplants in immunosuppressed animals to have characteristics of abnormal cells or by the addition of cells from an established cell line, which has been similarly modified or activated, to a normal leukocyte population. The preferred method of preserving the control cells is by lyophilization using an isotonic 10% trehalose solution.
