Stable lodinated polypeptide hormones prepared by polyacrylamide gel electrophoresis
Summary, in English
Iodination of several insulin and proinsulin preparations, human growth hormone and bovine pancreatic polypeptide was performed using H2O2 and lactoperoxidase or chloramine T. The iodination mixtures were fractionated by polyacrylamide gel electrophoresis at pH 9.15 in long gel rods followed by simple elution of the iodinated products from thin gel slices. With this method 125I tracers with long shelf life and high specific activity suitable for radioimmunoassays could easily be obtained.
