Exenatide and feeding: possible peripheral neuronal pathways.

abstract：:N-hydroxysuccinimide (NHS) esters of biotin are reported to react specifically with amino groups of peptides and proteins. However, we have found that these reagents can readily acylate other functional groups in specific peptide sequences under relatively mild conditions. We have extended our inquiry of sequence-depe...
