Each tube of mass spectrometry calibration standard contains four purified peptides: Leu-Enkephalin, Gonadoliberin, Angiotensin I, and Neurotensin. Conveniently dissolve the purified mass spectrometry calibration peptides right in the tube with buffer or matrix
solution, then analyze by MALDI-MS or ESI-MS. ProteoChem's Peptide Calibration Standard Set is packaged as 400 ug in one tube, with 100 ug of each of the four purified peptides for a total of 400 ug.
