| Genetic information | A targeting vector was designed to flank a 0.77-kb XbaI/EcoRI fragment containing the second exon of the Elavl1 gene with loxP sequences and placed adjacent to a loxP-flanked PMC-neo-pA neomycin resistance gene. 5' and 3' homology regions of 4.4 kb (EcoRI/XbaI) and 5.7 kb (EcoRI), respectively, were inserted on either side of the modified exon 2 sequences. Finally, the complete modified locus was subcloned at the 5' end of a herpes simplex virus thymidine kinase susceptibility gene for the negative selection of random integrants. Targeting procedures in 129/Ola embryonic stem cells and subsequent injections in C57BL/6 blastocysts for chimera production and germ-line transmission from three independent clones were performed using standard procedures. The HuR expression has been ablated by Cre excision of the targeted locus. |
