| molecularNote | A loxP-flanked neomycin resistance cassette (neo) was introduced 5' of the transcription initiation site of Hoxb4 and was subsequently deleted by transient Cre expression, leaving a single loxP site upstream of Hoxb4. Presence of the loxP site does not affect expression of the gene. |
