CD-1® Nude Mouse

Developed from the transfer of the nude gene from Crl:NU-Foxn1nu to a CD-1® mouse through a series of crosses and backcrosses beginning in 1979 at Charles River Laboratories, Wilmington, MA. The animal lacks a thymus, is unable to produce T-cells, and is therefore immunodeficient. The control model for the CD-1® Nude mouse is the CD-1® Heterozygous mouse. Note: See our isolator page for available immunocompromised animal housing units.
