Patent ID: 6899885

Claim:
An immunogenic composition comprising an isolated and purified 74 kD protein of M. catarrhalis , wherein the 74 kD protein has: (a) a molecular weight of approximately 74 kD as measured by mass spectrometry; (b) the amino-terminal amino acid sequence: Xaa Gly Gly Ser Gly Gly Ser Asn Pro Pro Ala Pro Thr (SEQ ID NO:1), where the first residue is not identified; and (c) an amino add composition of residues per mol of approximately Asp+Asn=104, Thr=58, Ser=44, Glu+Gln=67, Pro=27, Gly=77, Ala=56, Val=35, Met=6, Ile=21, Leu=40, Tyr=25, Phe=28, His=8, Lys=72, Arg=21, where Cys and Trp residues are not determined; wherein said immunogenic composition elicits an immune response in a mammalian host.
