the major labeled protein had a mol wt of about 33,000 on sodium dodecyl sulfate-polyacrylamide gel electrophoresis ( appropriate for the igf carrier protein subunit ) and gave a single predominant peak of radioactivity on sodium dodecyl sulfate-polyacrylamide gel electrophoresis and acid-urea gel electrophoresis that was immunoprecipitated by immune serum and comigrated with unlabeled proteins that bind [ 125i ] igf .
