Status | Available to order |
EMMA ID | EM:08489 |
International strain name | B6;129-Tdrd9tm1Embrp/Cnrm |
Alternative name | Tdrd9 KI (E257Q) cKO+Neo. |
Strain type | Targeted Mutant Strains : Knock-in |
Allele/Transgene symbol | Tdrd9tm1Embrp |

Information from provider
Provider | Ramesh PILLAI |
Provider affiliation | Grenoble Outstation, EMBL |
Genetic information | The Tdrd9 gene carries a single point mutation (E257Q) in the ATPase motif (exon 5) that is predicted to kill its activity. Presence of loxP sites flanking exons 3-5 allows generation of conditional KOs. Note that the Neo cassette used for selection of the targeted ES cell line (A9 ES cells) is retained in the mouse line. |
Phenotypic information | Homozygous:Homozygous KI males are infertile.Heterozygous:Males and females are viable and fertile. |
Breeding history | The founder male was generated with targeted A9 ES cells injected into C57BL/6N host embryos. The founder was crossed with C57BL/6N females. The F1 generation was genotyped for presence of the targeted allele. |
