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.

    Order Request Information

    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.

    Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.
