Dear Michael
BSA is not that bad for ESMS analysis. However a better standard in the MW
range that you are analysing is carbonic anhydrase (MW abot 29kDa, you
should find out the exact mass) that is commercially available.

told this is not a well behaved mass spec sample for ESI/MS. Does anyone
know of a good mass spec standard in this range? Many thanks in advance.
