Dual-Mode Repetitive-Sequence Standard is a mixture for the calibration of matrixassisted laser desorption and ionization-time-of-flight mass-spectrometers (MALDITOF 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 or negative mode. The mixture contains seven standard peptides. The compounds are listed in additional information together with their molecular weights. The standard is for research use only. It is not for use in diagnostic procedures.
