Genetic information	The -2663 to +93 region of the murine Gfap promoter, which has been shown to contain cis-regulatory elements required for astrocyte-specific expression, was fused to human TNF genomic sequences containing a deletion mutation of the codons encoding the 1st to the 12th amino acids of the mature 17-kDa TNF protein. This mutant TNF gene has previously been shown to produce a transmembrane TNF protein that remains bioactive against cellular targets in vitro and in vivo. The genomic DNA was then ligated to the 0.77-kb EcoRI-Sal1 fragment containing the 3' UTR and polyadenylation site of the beta-globin gene, which replaces TNF 3' UTR sequences, thought to negatively regulate mRNA stability and translational efficiency. In this transgenic line, exogenous TNF protein production could be demonstrated by positive immunostaining of astrocytes in the spinal cord and brain sections using a polyclonal anti-human TNF antiserum.
Phenotypic information	Homozygous: n/a Heterozygous: Neurologic disorder manifested by ataxia, seizures, and paralysis and bearing histologic evidence of chronic CNS inflammation and degeneration; 100% phenotypic penetrance.

Order

Availabilities

Requesting frozen sperm or embryos is generally advisable wherever possible, in order to minimise the shipment of live mice.

Frozen embryos. Delivered in 4 weeks (after paperwork in place). €1740^*
Rederivation of mice from frozen stock, delivery time available upon request . €3880^*

Due to the dynamic nature of our processes strain availability may change at short notice. The local repository manager will advise you in these circumstances.

^* In addition users have to cover all the shipping costs (including the cost for returning dry-shippers, where applicable).
