| molecularNote | Neo-LacZ cassette was inserted into ATG initiation codon to disrupt the coding frame. The targeting vector contains a mutation to change ATG to ATC and a replacement of 203 bp downstream of ATG with the LacZ-Neo resistance cassette. Northern and Western blot analysis confirmed the absence of transcription and translation. |
