Production of radioiodinated T3 and T4

摘要

The chloramine T procedure is employed to provide radioiodinated T3 and radioiodinated T4 from T3 and T4, respectively, at specified pHs and mole ratios to provide for long shelf life. T3 is also radioiodinated to high specific activity radioiodinated T4, and purified after a specified waiting period to remove radioactive non-antigenic contaminants and thereby provide a long shelf life.
