Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
A method of diminishing the incidence of shipping fever in livestock which comprises administering to subject livestock an amount of a water soluble form of hIL-2 in the range of above about 10 3 and below about 10 6 u/kg/day over a period of from about 14 to 30 days, wherein the water soluble form of hIL-2 is hIL-2 covalently bonded through one or two amino acids via a coupling agent to polyethylene glycol having a molecular weight in the range of from about 500 to 200,000, and wherein no more than about 50 moles of polyethylene glycol are employed per mole hIL-2.
Claim 2
Independent Claim
