The S5/S6 transmembrane domains are deleted from the transient receptor potential cation channel, subfamily A, member 1 gene. Homozygous mice show reduced sensitivity to pain. This strain may be useful in functional studies of cation channels and the neurological processes of pain.

The S5/S6 transmembrane domains are deleted from the targeted gene. Homozygous mice show reduced sensitivity to pain. They are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This strain may be useful in functional studies of cation channels and the neurological processes of pain.
LoxP sites were placed on either side of the exons that encode for the S5/S6 transmembrane domains of the gene followed by an FRT-flanked self-excising neomycin resistance cassette placed in the opposite transcriptional orientation. The mutation was created with 129S6/SvEvTac-derived TC1 embryonic stem (ES) cells. The neomycin cassette was excised through a cross with a Gt(ROSA)26Sor FLP strain on an unknown genetic background and the floxed exons were deleted through a cross with a Cre strain with a widespread pattern of expression on an unknown genetic background. Cre has been selectively bred away from the line.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
