Research areas: Research Tools, Sensorineural Research

Development

This targeted mutation was generated in 129P2/OlaHsd derived E14 ES cells and the resulting mice were crossed to Tg(EIIa-cre) bearing mice to excise the loxP flanked pgkneo (LNL) cassette. Although this transgene was generated in FVB/N mice, it was backcrossed onto C57BL/6J prior to this cross. The offspring were intercrossed and the transgene was selectively bred out of this line. Thus, this STOCK background is predominantly C57BL/6J and 129P2/OlaHsd. In 2007 sperm were cryopreserved from homozygous males.

The plasmid that was used to generate this mutation is banked and described at Addgene.
