1. A method for detecting a transmissible spongiform encephalopathy (TSE) agent comprising:
(a) contacting isolated leucocytes from a subject with an antibody selective for PrPSc, wherein the antibody is produced by hybridoma ATCC PTA-7393;
(b) contacting the isolated leucocytes with anti-immunoglobulin coated beads;
(c) examining the beads and leucocytes for a rosetting effect;
wherein a rosetting effect indicates detection of the TSE agent.
