Specific Binding Members Against Synaptophysin
First Claim
1. A specific binding member that binds synaptophysin and which comprises:
- an antibody VH domain selected from the group consisting of the C1-3 VH domain (SEQ ID NO.
2) and a VH domain comprising a VH CDR3 with the amino acid sequence of SEQ ID NO. 12 and optionally one or more VH CDR'"'"'s with an amino acid sequence selected from SEQ ID NO. 10 and SEQ ID NO. 11; and
/oran antibody VL domain selected from the group consisting of the C1-3 VL domain (SEQ ID NO.
4) and a VL domain comprising one or more VL CDR'"'"'s with an amino acid sequence selected from SEQ ID NO. 13, SEQ ID NO. 14 and SEQ ID NO. 15.

Abstract
The present invention provides specific binding members that bind synaptophysin and which comprise: an antibody VH domain selected from the group consisting of the C1-3 VH domain (SEQ ID NO. 2) and a VH domain comprising a VH CDR3 with the amino acid sequence of SEQ ID NO. 12 and optionally one or more VH CDR'"'"'s with an amino acid sequence selected from SEQ ID NO. 10 and SEQ ID NO. 11; and/or an antibody VL domain selected front the group consisting of the C1-3 VL domain (SEQ ID NO. 4) and a VL domain comprising one or more VL CDR'"'"'s with an amino acid sequence selected from SEQ ID NO. 13, SEQ ID NO. 14 and SEQ ID NO. 15. The invention further provides related materials such as nucleic acids, kits and compositions, and also methods of use of the binding member, for instance in targeting entities to hepatic stellate cells which are implicated it liver fibrosis.

19. A method of obtaining a specific binding member that binds synaptophysin, the method comprising
providing by way of addition, deletion, substitution or insertion of one or more amino acids in the amino acid sequence of the C1-3 VH domain (SEQ ID NO. 2) one or more VH domains each of which is an amino acid sequence variant of the C1-3 VH domain, optionally combining one or more VH domain amino acid sequence variants thus provided with one or more VL domains to provide one or more VH/VL combinations; - and/or
providing by way of addition, deletion, substitution or insertion of one or more amino acids in the amino acid sequence of the C1-3 VL domain (SEQ ID NO.
4) a VL domain which is an amino acid sequence variant of the C1-3 VL domain, and combining one or more VL domain amino acid sequence variants thus provided with one or more VH domains to provide one or more VH/VL domain combinations;and testing the VH domain amino acid sequence variants or VH/VL combination or combinations for to identify a specific binding member that binds synaptophysin. - View Dependent Claims (21, 22, 23, 24, 25)

20. A method of obtaining a specific binding member that binds synaptophysin, which method comprises:
-
providing starting nucleic acids encoding one or more VH domains which either comprise a CDR3 to be replaced or lack a CDR3 encoding region, and combining said starting nucleic acid with a donor nucleic acid encoding the VH CDR3 amino acid sequence of SEQ ID NO. 12 such that said donor nucleic acid is inserted into the CDR3 region in the starting nucleic acid, so as to provide product nucleic acids encoding VH domains;
orproviding starting nucleic acids encoding one or more VL domains which either comprise a CDR3 to be replaced or lack a CDR3 encoding region, and combining said starting nucleic acid with a donor nucleic acid encoding the VL CDR3 amino acid sequence of SEQ ID NO. 15 such that said donor nucleic acid is inserted into the CDR3 region in the starting nucleic acid, so as to provide product nucleic acids encoding VL domains; expressing the nucleic acids of said product nucleic acids encoding VH domains and optionally combining the VH domains thus produced with one or more VL domains to provide VH/VL combinations, and/or expressing the nucleic acids of said product nucleic acids encoding VL domains and combining the VL domains thus produced with one or more VH domains to provide VH/VL combinations; selecting a specific binding member comprising a VH domain or a VH/VL combination that binds synaptophysin; and recovering said specific binding member that binds synaptophysin and/or nucleic acid encoding the specific binding member that binds synaptophysin.
