title: Demonstration of murine pancreas elastase and its interstrain variation by isoelectric focusing.
abstract: Isoelectric focusing between pH 9 and 11 was used for separation of murine pancreas proteases. One of these proteases is characterized by its preference for N-acetyl-L-alanine-alpha-naphthylester as substrate and by its genetic linkage to bt, a coat color marker of chromosome 15. This protease was identified as elastase, and is probably elastase-1 (ELA-1). Because of the simple procedure and the excellent reproducibility of the focusing pattern, ELA-1 is recommended as a useful marker for mouse chromosome 15.
