Linear dynamic range of templates. The range of template RNA was from (a) 0.78 ng to 100 ng or (b) 25 ng to 500 ng at serial dilutions (1:2) for each data point, which represents the average of triplicate reactions. (a) alphas (square; primers Calpha/gen-F + Calpha/Sec-R; probe P1.Calpha), alpham (diamond; primers Calpha/gen-F + Calpha/Mem-R; probe P1.Calpha) and beta-actin (circle; primers beta-actin-F + beta-actin-R; probe P2.beta-actin) expression in human tonsillar B cells. R2 values are 0.999, 0.998 and 0.997, respectively. (b) Human plasma cell antigen-1 (HPC1) (filled circle; primers HPC1-F + HPC1-R; probe P1.HPC1) and beta-actin (diamond; primers as for a) expression in human plasmacytoma cell line NCI-H929. R2 values are 0.993 and 0.997, respectively.
