The Peptide Calibration 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 700 and 3200 Da. The mixture contains nine standard peptides (Bradykinin Fragment 1-7, Angiotensin II, Angiotensin I, Substance P, Bombesin, Renin Substrate, ACTH clip 1-17, ACTH clip 18-39, Somatostatin 28).
It is recommended to use this calibration standard in combination with α-Cyano-4-hydroxycinnamic acid (HCCA) (Part. No. 8201344) as matrix.
The Peptide Calibration 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.
