Real-time PCR analysis of selected genes in bone marrow of wild-type andSiat1ΔP1 mice. Expression of selected genes (A) and different mRNA forms of ST6Gal1 (B) were measured by real-time PCR relative to RPL32, a ribosomal protein mRNA, as reference standard. The procedure involved in analysis of 1 μg total RNA in duplicate. Sensitivity limit is denoted by the dotted line. Liver RNA is shown for comparison. Error bars represent 1 standard deviation from the mean of each group.
