he average mean channel shifts was 801 for the lymphocytes (range, 318 to 1202) and 705 for the flow beads (range, 620 to 745) .
The standard deviation was 302 for the lymphocytes and only 52 for the flow beads .
The results indicated that the amount of HLA antigen coated on the beads was similar to the average amount of antigen on the lymphocytes.
