| description | ES cell line = 16.7, a stable 40XX subclone of ES cell line EL16. 16.7 cells carry one X chromosome from 129 and the other from M. m. castaneus. |
| molecularNote | A floxed neo cassette replaced DXPas34. The neo cassette was subsequently removed via transient cre expression. Absence of a 129-specific BamHI restriction pattern indicated that the 129-derived X chromosome was targeted. |
