Dear ABRF-er,

Repeated N-terminal sequence analysis of a partly known protein on a
Prosice 494 has given glycine instead of an expected asparagin. Differen=
t
batches gave the same result. I wonder if someone has seen this and/or ca=
n
explain the type of modification of asparagin that gives the same retenti=
on
time as Gly.
Thank you in advance.
