Hi Folks,

I'm trying to do MALDI on a pretty big protein (90k). What are the mass
standards for that range? Are there any matrixes other than sinapinic acid
that are worth trying for this big protein? Or there are some special sample
preparation methods? Is it true that I should not expect a good mass accuracy
at this high end?

Thanks in advacne!
