Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
53 words
A preparation for treatment of allergic patients sensitive to ragweed pollen, comprising ragweed antigen E polymerized with glutaraldehyde and being composed essentially of water-soluble polymers thereof of molecular weights from 200,000 to 20,000,000, said preparation being substantially free of unpolymerized ragweed antigen E and polymers thereof having molecular weights of less than 200,000.
Claim 2
Dependent Claim
53 words
A preparation for treatment of allergic patients sensitive to ragweed pollen, comprising ragweed antigen E polymerized with glutaraldehyde and being composed essentially of water-soluble polymers thereof of molecular weights from 200,000 to 20,000,000, said preparation being substantially free of unpolymerized ragweed antigen E and polymers thereof having molecular weights of less than 200,000.
Claim 3
Independent Claim
64 words
A method of treating an allergic patient sensitive to ragweed pollen to alleviate the allergy, comprising administering to said patient by intracutaneous injection ragweed antigen E polymerized with glutaraldehyde and being composed essentially of water-soluble polymers thereof of molecular weights from 200,000 to 20,000,000, said preparation being substantially free of unpolymerized ragweed antigen E and polymers thereof having molecular weights of less than 200,000.
Claim 4
Independent Claim
64 words
A method of treating an allergic patient sensitive to ragweed pollen to alleviate the allergy, comprising administering to said patient by intracutaneous injection ragweed antigen E polymerized with glutaraldehyde and being composed essentially of water-soluble polymers thereof of molecular weights from 200,000 to 20,000,000, said preparation being substantially free of unpolymerized ragweed antigen E and polymers thereof having molecular weights of less than 200,000.
