Strain Description

Phenotype
Coat color is an off-white. Individual hairs are largely devoid of pigment, but small masses of sepia material or occasional granules occur in the proximal portion. The agouti band and tip of hair are completely devoid of pigment. Older deer mice are lighter in color than the young. Animals- superficially resemble albinos. Ivory animals gave a greater ability to oxidize tyrosine and dihydroxyphenylalamine than do albino deer mice.

MMRRC Genetic QC

MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact mmrrc@missouri.edu. Older strains may not have this information.

Order Request Information

Availability Level

Male mice were obtained from the Peromyscus Genetic Stock Center as part of a long term project to develop cropreservation techniques for Peromyscus. Sperm have been cryopreserved and are available. However, cryorecovery techniques have yet to be developed.
