Peptide Calibration Standard II is a mixture for the calibration of matrix-assisted laser
desorption and ionization-time-of-flight mass-spectrometers (MALDI-TOF MS).
Product contains 5 vials; each vial contains a mix of lyophilized peptides as TFA salts
for 125 μl solution. It allows calibrations (5 x 125 calibration points) and testing of
MALDI-TOF mass spectrometers in a mass range between ~500 and 3500 Da and
can be used for calibration in positive mode. The mixture contains seven standard
peptides. The compounds are listed in the additional information together with their
molecular weights.
The standard is for research use only. It is not for use in diagnostic procedures.
