Rabbit polyclonal antibodies (EU102) to a 352-residue region (4215-4567) that contains Ig domains 18 and 19 and 150 amino acid residues beyond, and is just N-terminal to the PEVT/K region. On the basis of the Ce titin gene structure, it would be expected that EU102 would react with the 2.2 MDa and 1.2 MDa isoforms.
