Expression of the major Fmr1 isoforms during mouse brain development.

Brains were harvested in triplicate from male littermates and Fmr1 transcript isoforms were quantified as described in Materials and Methods. The data for all time points (except P7) are averages of biological triplicates and error bars represent the standard deviation in the biological triplicates. The values for P7 are an average of two brains, and the error bars represent the range in data.
