Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
54 words
Nucleic acid encoding a polypeptide fusion comprising a ligand binding partner protein containing more than one polypeptide chain, wherein the ligand binding partner protein is not a platelet growth factor receptor or an insulin receptor, one of said chains being fused to an immunoglobulin constant region through C- or N-terminal amino or carboxyl groups.
Claim 2
Dependent Claim
54 words
Nucleic acid encoding a polypeptide fusion comprising a ligand binding partner protein containing more than one polypeptide chain, wherein the ligand binding partner protein is not a platelet growth factor receptor or an insulin receptor, one of said chains being fused to an immunoglobulin constant region through C- or N-terminal amino or carboxyl groups.
Claim 3
Dependent Claim
98 words
Nucleic acid encoding a polypeptide fusion of a ligand binding partner protein and an immunoglobulin chain, wherein the ligand binding partner protein is not a platelet growth factor receptor or an insulin receptor, said ligand binding partner protein and said immunoglobulin chain being fused through C- or N-terminal amino or carboxyl groups, and said fusion further comprising an additional fusion of an agent selected from the group consisting of a multiple subunit (chain) polypeptide, a portion of an immunoglobulin superfamily member, a toxin and a polypeptide therapeutic agent not otherwise associated with an immunoglobulin, and an immunoglobulin chain.
Claim 4
Dependent Claim
98 words
Nucleic acid encoding a polypeptide fusion of a ligand binding partner protein and an immunoglobulin chain, wherein the ligand binding partner protein is not a platelet growth factor receptor or an insulin receptor, said ligand binding partner protein and said immunoglobulin chain being fused through C- or N-terminal amino or carboxyl groups, and said fusion further comprising an additional fusion of an agent selected from the group consisting of a multiple subunit (chain) polypeptide, a portion of an immunoglobulin superfamily member, a toxin and a polypeptide therapeutic agent not otherwise associated with an immunoglobulin, and an immunoglobulin chain.
Claim 5
Dependent Claim
22 words
The nucleic acid of claim 2 wherein said ligand binding partner is LHR and said agent in said additional fusion is CD4.
Claim 6
Dependent Claim
39 words
Nucleic acid encoding a polypeptide fusion comprising a ligand binding partner protein which comprises a LHR and an immunoglobulin chain, in which the ligand binding partner protein and immunoglobulin are fused through C- or N-terminal amino or carboxyl groups.
Claim 7
Dependent Claim
39 words
Nucleic acid encoding a polypeptide fusion comprising a ligand binding partner protein which comprises a LHR and an immunoglobulin chain, in which the ligand binding partner protein and immunoglobulin are fused through C- or N-terminal amino or carboxyl groups.
Claim 8
Dependent Claim
21 words
The nucleic acid of claim 4 wherein said immunoglobulin chain is obtained from IgG1, IgG2, IgG3, IgG4, IgE, IgD or IgM.
Claim 9
Dependent Claim
19 words
The nucleic acid of claim 4 wherein in said LHR the transmembrane and the cytoplasmic domains have been deleted.
Claim 10
Dependent Claim
32 words
The nucleic acid of claim 6 wherein the transmembrane and cytoplasmic domain deleted LHR is fused at its C-terminus to the N-terminus of an human IgG immunoglobulin heavy chain constant region sequence.
Claim 11
Dependent Claim
55 words
The nucleic acid of claim 7 wherein the transmembrane and cytoplasmic domain deleted LHR is fused at its C-terminus to the N-terminus of an IgG immunoglobulin sequence beginning in the hinge region just upstream of the papain cleavage site at residue 216, taking the first residue of the heavy chain constant region to be 114.
