Hello,
I realize this is a very simplified question, but I'm wondering if it is possible to have a scan count for an individual protein of "0" (zero) but still have a peptide count of 1 for the same protein?

LTQ mass spec was used.

Thanks for any help.

Dear All :
I need your help to deside to go for Maldi TOF From bruker,
or to go for MAldi LTQ xl from Thermo,
pionts i neeed help for it are :
1- What is better for my application ( protomic mass spectrometry investigation. )

2- If you new approximate price for Bruker MAldi TOF it will help also.
