  • Thyroxin-binding HSA fragments
    Patent number: 5698517
    Abstract: Modified forms of human serum albumin (HSA) wherein the arginine at position 218 is substituted by a less basic amino acid show strong thyroxin-binding activity. These modified forms of HSA and fragments thereof are useful in binding thyroxin in standard assays for free thyroxin concentration and in treating conditions characterized by higher-than-desired levels of free thyroxin in animal subjects.
    Type: Grant
    Filed: March 21, 1994
    Date of Patent: December 16, 1997
