Bruce and Ben review Sam's latest GemStone models for analyzing T-cells. After showing how little Sam really had to know to build his models, the guys explore the amazing relationships of T-cell markers that are revealed by the analysis. By the end of the session, Sam's model shows 33 correlated T-cell markers in a single overlay plot. Data for Sam's model was kindly provided by Margaret Inokuma, Scientist / Biological Research and Development, BD Biosciences.
