IRESite notes about verification of plasmid sequence:
The complete sequence of IRES element was determined by sequencing using Fluc_seq_reverse
(AGGAACCAGGGCGTATCTC) primer.

For detailed verification of whole plasmid sequence see item IRESite Id: 413.

The plasmid was used as the negative control for experiments in article Enhancement of IRES- Mediated
Translation of the c-myc and BiP mRNAs by the Poly(A) Tail Is Independent of Intact eIF4G and PABP (Thoma et
al., 2004; PMID: 15383282).
