The Protein Calibration Standard I 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 4000 and 20000 Da. The mixture contains four standard proteins. The compounds are listed in the following table together with their molecular weights.
It is recommended to use this calibration standard in combination with α-Cyano-4-hydroxycinnamic acid (HCCA) (Part. No. 8201344) as matrix.
The Protein Calibration Standard I 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.
