Subject: NBD peptide
>Hello!
>We have synthesized a peptide with a fluorescent dye, NBD
>(7-nitrobenz-2-oxa-1,3-diazole) attached at the N-terminus via an
>aminohexanoic acid spacer arm. We have a product which looks OK by all
>criteria except the MALDI-TOF shows the expected molecular peak but
>two sizable satellites corresponding to M-16 and M-32. These peaks do
>not appear in the spectrum of the dye-free peptide. Any ideas what
>they may be? Thank you for your help.
