| description | ES Cell line = B6JN/1 mouse embryonic stem cells, derived from a (C57BL6/J Jcl) x (C57BL6/N Jcl) embryo |
| molecularNote | A loxP site was inserted 3 the J alpha 18 (J alpha 281) gene segment and an FRT-flanked neomycin cassette followed by a second loxP site was placed 3 to the gene segment. The neomycin selection cassette was removed via FLP-mediated recombination. The J alpha 18 segment and neo cassette were removed via cre-mediated recombination of the loxP sites. |
