Flexible antibodies with nonprotein hinges
Proceedings of the Japan Academy, Series B, 2011 There is a significant need for antibodies that can bind targets with greater affinity. Here we describe a novel strategy employing chemical semisynthesis to produce symmetroadhesins: antibody-like molecules having nonprotein hinge regions that are more flexible and extendible and are capable of two-handed binding.
