B6Rcc.129-Cd44tm1.1Ugu Spp1tm1Rit/Cnrm
Status | Available to order |
EMMA ID | EM:01990 |
International strain name | B6Rcc.129-Cd44tm1.1Ugu Spp1tm1Rit/Cnrm |
Alternative name | C57 BL/6RCC CD44v6v7-/- OPN-/- |
Strain type | Targeted Mutant Strains : Knock-out |
Allele/Transgene symbol | Spp1tm1Rit, |
Gene/Transgene symbol | Spp1 |
Information from provider
Provider | Ursula Günthert |
Provider affiliation | Institut für Pathologie, University of Basel |
Genetic information | A loxP site was inserted 3' of exon v6 and a neomycin resistance cassette, with a 5' loxP site, was inserted 5' of exon v6 of the Cd44 gene. During insertion, 1.6 kb of sequence was lost in the exon v7 region. Cre recombinase was transiently expressed in ES cells allowing the removal of neomycin cassette and exon v6. Mice lack both exon v6 and v7. The neomycin cassette from pMC1neo was inserted into the EagI site in exon 6 of the Spp1 (secreted phosphoprotein 1; formerly: Opn, osteopontin) gene (a 4.8 kb fragment from 129 mice), that had been cloned into pBluescript (Rittling et al., 1998). |
Phenotypic information | Cd44v6v7-/-: Strongly reduced symptoms in autoimmune diseases and haemopoiesis. Opn (Spp1)-/-: Strongly reduced symptoms in autoimmune diseases and impaired bone remodeling. |
Breeding history | 10 generations backcrossed onto C57BL/6Rcc; currently bred as C57BL/6Rcc Cd44v6v7-/- Opn-/-. |
