The concentration of the VDR mRNA was 10(-8) to 10(-7) g/g of total RNA in cell-sorted monocytes and in in vitro activated lymphocytes , but only 10(-12) g/g of total mRNA in resting lymphocytes , establishing that the VDR mRNA determined by our method in PBMCs is due to constitutive expression in monocytes .
