a). Hybridization pattern for the human autoantigen probe set (with RNA isolated from normal PBMC), PM = Perfect match, MM = Mismatch. b). Hybridization pattern for probe set human carboxy ester lipase-like protein (with RNA isolated from leukemic LGL. PM = Perfect match, MM = Mismatch Note: Even though the gene is present in trace amounts, it is calculated as absent because of the high background caused by MM hybridization.
