Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Targeted Mutation Mating System Heterozygote x Heterozygote (Female x Male) Species laboratory mouse Donating Investigator Gregg Homanics, University of Pittsburgh Generation N3+ (10-OCT-07) Strain Description
Mice homozygous for this GABAA-R alpha4F allele are viable and fertile. These mutant mice have loxP sites flanking exon 3 of the targeted gene. When bred to Cre-recombinase expressing mice, offspring will have a deletion of exon 3 in the cre expressing tissue(s). These "floxed" mice may be useful in neurological studies including behavior and neurotransmitter function.Of note, several strains bearing gamma-aminobutyric acid (GABA-A) receptor mutations are available from this donating investigator (Dr. Gregg Homanics, University of Pittsburgh), including Gabra1 (Stock No. 004318), Gabra4 (Stock No. 006874), Gabra6 (Stock No. 002710), Gabrb3 (Stock No. 002711), Gabrd (Stock No. 003725), and Gabrg2 (Stock No. 003137).
Strain Development
A targeting vector was designed to place a loxP site upstream and a frt-flanked neomycin resistance gene and loxP site downstream of exon 3 of the targeted gene. The construct was electroporated into (129X1/SvJ x 129S1/Sv)F1-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were microinjected into C57BL/6J blastocysts. Chimeric mice were bred to C57BL/6J females. Offspring with the "floxed" exon 3 allele and neomycin cassette (Fneo) were bred to actin-FLPe mice (on a mixed C57BL/6J and SJL genetic background). Offspring with "floxed" exon 3 and excised neo allele (F) were subsequently backcrossed to C57BL/6J for 2 generations. Mice were then backcrossed to an EIIa-Cre transgenic mouse strain (C57BL/6J congenic background, see Stock No. 003724). The resulting mice still containing the non-recombined "floxed" exon 3 (F) allele that were negative for the cre transgene were bred to C57BL/6J for two more generations prior to arrival at The Jackson Laboratory. Upon arrival, mutant mice were bred to C57BL/6J for at least three generations.

| Standard Supply | Repository-Live. A collection of over 1000 strains maintained as live colonies. Individual colonies are sized to meet current customer demand. Delivery for orders of 10 mice or less ranges on average from one to eight weeks; mice are generally shipped between four to six weeks of age with a maximum shipping age of ~nine weeks. Colony sizes do not generally support stringent age specifications for large volumes of mice; however custom orders and larger quantities of mice are easily arranged. Estimated ship dates for all orders provided within 48 hours of order placement. |
