A construct comprised of a 9.4 kb sequence of Olfr16 from 129/Sv, including all 3 exons, with an IRES-taulacZ-neo cassette 3 base pairs downstream of the stop codon, inserted into 5G3 via non-homologous recombination subsequent to electroporation in E14 ES cells. A cross with a mouse bearing Tg(EIIa-cre)C5379 excised the floxed neo. (J:78878)
