SPECIES AND TISSUE-SPECIFIC VARIATIONS IN DISTRIBUTION OF MAMMALIAN TRYPTOPHANYL-tRNA SYNTHETASE: AN ABNORMAL HIGH CONTENT IN BOVINE PANCREAS

Summary

    The content of tryptophanyl-tRNA synthetase has been determined in human, bovine, rat and rabbit liver and pancreatic extracts by direct radioimmunoblotting with I25I-labelled monoclonal antibody. It was in bovine but not in other pancreas that the unusually high amount of tryptophanyl-tRNA synthetase was estimated (about 0.2 %). According to the indirect immunofluorescent method, bovine tryptophanyl-tRNA synthetase is located in exocrinic part of the pancreatic gland.
