Accurate pre-mRNA splicing using a nuclear extract from Bombyx mori fat body.


A cell-free pre-mRNA splicing system was developed from the nuclear extract of Bombyx mori fat bodies. The synthetic pre-mRNA from the cytoplasmic actin gene of B. mori (BmA3 ) was used as a substrate for in vitro splicing. The pre-mRNA was accurately spliced in the nuclear extract prepared from the fat body. Sequencing of the amplicon by RT-PCR revealed… (More)
