Allele Symbol: Cd55tm1Song Name: CD55 antigen / targeted mutation 1, Wen-Chao Song Alteration at locus: Knockout |
Genetic Alterations:
a neo cassette replaced exons 2-4.
Genotype Determination:
ES Cell Line: TL-1
Phenotype:
Homozygous phenotype: There is no
spontaneous phenotype; however, the following may be observed:
-
increased susceptibility of knockout mice to anti-glomerular basement
membrane (glomerulonephritis)
- deletion of DAF exacerbates autoimmune
disease development in MRL/lpr mice
- DAF knockout mice display
exarcerbated disease progression in the experimental autoimmune
encephalomyelitis (EAE) model.
Heterozygous phenotype: no phenotype
Strain Type:
Founder genetic background: C57BL/6 x 129
Strain genetic background: BALB/cJ
Strain Development:
Donor: Wenchao Song, Ph.D., University of Pennsylvania, School of Medicine

Mice recovered from a cryo-archive will have health surveillance performed on the
resuscitated animals.
Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.
* Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

| MMRRC Item # | Description | Distribution Fee/unit (US $) |
Units |
|---|---|---|---|
| 030201-MU/H-Resus | Resuscitation from cryopreserved material | $1,850.00 | litter a |
| 030201-MU/H-Sperm | Cryopreserved spermatozoa | $400.00 | aliquot b |
a The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one breedable mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC repository will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC repository.
b An aliquot contains sufficient material (volume and concentration) for at least two IVF or several artificial inseminations (based on our procedures). The MMRRC makes no guarantee concerning success of these procedures when performed outside the MMRRC facilities.
