Formatting sequence information for emails (splice modifying oligo designs)

To email sequence information for design of a splice-modifying Morpholino, write introns in lower case and exons in upper case and write the sense sequence 5'-3'. If you show a start codon, put parentheses around it. Here is an example:


All I need for the design are 10 exonic and 25 intronic bases, like this:
