What is the Source of the Atomic Weight Information in BPV Flex Software?

For research use only. Not for use in diagnostic procedures.

Answer

BPV Flex software uses the same source of atomic weight information as BioPharmaView™ software.  The theoretical value required for the intact workflow uses the average molecular weight; the peptide workflow uses the monoisotopic weight.

In the release notes for BPV Flex software 2.1, the source of the atomic weights used can be found on page 5: Coursey, J.S., Schwab, D.J., Tsai, J.J., and Dragoset, R.A. (2015), Atomic Weights and Isotopic Compositions (version 4.1). [Online], Available: http://physics.nist.gov/Comp.
