Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
42 words
An isolated nucleic acid encoding a polypeptide having 95% identity to the human α1 (XVIII) collagen encoded by the nucleic acid sequence of SEQ ID NO:4, said polypeptide comprising the sequence Gly-X-Y-Gly-X'-Y', where X, Y, X', and Y' represent any amino acid.
Claim 2
Dependent Claim
42 words
An isolated nucleic acid encoding a polypeptide having 95% identity to the human α1 (XVIII) collagen encoded by the nucleic acid sequence of SEQ ID NO:4, said polypeptide comprising the sequence Gly-X-Y-Gly-X'-Y', where X, Y, X', and Y' represent any amino acid.
Claim 3
Dependent Claim
24 words
The nucleic acid of claim 1, said nucleic acid encoding human α1 (XVIII) collagen encoded by the nucleic acid sequence of SEQ ID NO:4.
Claim 4
Dependent Claim
9 words
A plasmid comprising the nucleic acid of claim 1.
Claim 5
Dependent Claim
23 words
The plasmid of claim 3, said plasmid further comprising an expression control sequence capable of directing expression of said α1 (XVIII) collagen polypeptide.
Claim 6
Dependent Claim
