The Protein Standard II allows calibration and testing of matrix-assisted laser desorption and ionization time-of-flight mass spectrometers (MALDI-TOF MS). It is designed for calibration of method parameter files of MALDI-TOF mass spectrometers in a low mass range between 10000 and 70000 Da. The mixture contains three standard proteins. The compounds are listed in the following table together with their calculated mass numbers.
The Protein Standard II is supplied in five tubes per package allowing 5x250 calibration spots.
The standard is for research use only. It is not for use in diagnostic procedures.
The tube box is shipped at ambient temperatures. It is recommended to store the standard on arrival at less than 0 °C.
