SNRPN transcription.
(A) Diagram of exons 2 and 3 of SNRPN showing polymorphicBstUI site and flanking primers. (B) SNRPN RT-PCR products from 5 heterozygous bone marrow samples after digestion withBstUI. In each case imprinted transcription ofSNRPN is demonstrated. Lane M shows pUC DNA digested with MspI.
