A mass-spectroscopic method for measuring des-Leu albumin - A novel marker for chronic pancreatitis

► Des-Leu albumin is a truncated form of albumin formed in pancreatitis. ► We have developed a LC-MS/MS method for quantifying this protein. ► Des-Leu albumin is the major form of albumin present in patients with pancreatitis. ► This protein is a potential novel biomarker for chronic pancreatitis.
