Features a convenient selection of pre-qualified standard peptides, proteins, matrices, and solvents for calibrating and testing matrix assisted laser desorption ionization (MALDI) mass spectrometers.

Configured for analyzing complex mixtures of proteins and peptides (700 to 66,000 Da), this kit is ideal for evaluating unknown samples or samples containing a broad range of molecular weights. Applications include calibration, tuning, and sensitivity testing of MALDI instruments from all manufacturers.
