    New England Biolabs swai
    Diagrammatic representation of an A-homology (A-box) arm. The example chosen is the gene Chat (encoding choline acetyltransferase). The 5′ primer used in the amplification of the Chat A-box was 5′ GGCGCGCC AAGGTGCTCTAGTGCTCTGATCCCAG 3′. The first eight nucleotides in this sequence do not correspond to the genomic sequence of Chat but represent an added Asc I recognition site sequence 5′-GGCGCGCC-3′. A key step in designing the 5′ primer is the addition of an AscI or <t>MluI</t> enzyme site at the front of the primer. It serves in a later step when the A-homology arm is ligated into an AscI and <t>SwaI-digested</t> pLD53.SC2 vector at its AscI or SwaI cloning sites. If an internal AscI recognition sequence is present within the homology sequence (can be checked with the DNASTAR program), a MluI recognition site, 5′-ACGCGT-3′, should be added to the end of the primer instead. The enzyme MluI is then used in the digestion step. The 3′ primer used for Cha t in the homology amplification step was 5′ CCTAGCGATTCTTAATCCAGAGTAGC 3′. This is the reverse-complement of the 3′ sequence highlighted in the figure.
