Patent ID: 7090847

Claim:
A method for preparing an antibody or a fragment thereof that comprises the antigen binding site of the antibody, wherein said antibody binds to: (i) a mammalian IL-B30/p40 complex comprising an IL-B30 subunit (SEQ ID NO:2 or 4) and a p40 subunit (SEQ ID NO:6 or 8), or (ii) a fusion protein comprising the IL-B30 subunit (SEQ ID NO:2 or 4) and the p40 subunit (SEQ ID NO:6 or 8); said method consists of: (a) raising an antibody to said IL-B30/p40 complex or a polypeptide that comprises at least 11 contiguous amino acids from said p40 subunit and at least 11 contiguous amino acids from the IL-B30 subunit, (b) confirming that said antibody binds to the IL-B30/p40 complex or fusion protein; and (c) optionally preparing said fragment from said antibody.
