mass spectra

[elhddad]

please could any professional body help me to answer the next question:
Describe how you might use tandem mass spec to detect and then locate a phosphorylated amino acid in a tryptic peptide?

I'm afraid that you really need to discuss this question with your lecturers in conjunction with your course notes on MS/MS to obtain the answer to this question.

Providing you with an answer would not help you understand the fundamentals of MS/MS and I'd suggest you research the answer yourself. You should know where to seek further information on the subject.

Hi BertiWooster

Nice to hear from you. I'm still around and as busy as ever although I still find time to post on AB quite often. Very little stops me posing on AB - right now, I'm on a USA island state where I'm a senior academic. I'll be back in the UK on Wednesday

[theprof]

posing? Should be posting. No comments from my critics please!
