Patent ID: 8465742

Claim:
An isolated V H H antibody fragment obtained from a V H H library prepared by a method comprising: (1) immunizing a camelid with whole venom or an extract thereof; (2) isolating nucleic acid sequences encoding the variable heavy fragment from the immunized camelid; and (3) transforming a suitable host with the nucleic acid sequences to prepare a recombinant V H H library comprising V H H antibody fragments, wherein the V H H antibody fragments comprise a heavy chain complementarity determining region 1 (CDR1) comprising the amino acid sequence of SEQ ID NO:5; a heavy chain complementarity determining region 2 (CDR2) comprising the amino acid sequence of SEQ ID NO:9; and a heavy chain complementarity determining region 3 (CDR3) comprising the amino acid sequence of SEQ ID NO:11.
