Abstract
The invention generally relates to compositions and methods for treating snake envenomation in animals, including humans. In some aspects, the invention provides therapeutic compositions that contain one or more toxin binding molecules including, for example, anti-toxin antibodies and binding fragments.
Claims16
A single-domain antibody (sdAb) that binds to snake venom metalloproteinase (SVMP), comprising an amino acid sequence which is at least 70% identical to SEQ ID NOs. 1 or 2.
A single-domain antibody (sdAb) that binds to snake venom metalloproteinase (SVMP), wherein the sdAb comprises at least one single-variable region that includes a plurality of complementarity-determining regions (CDRs) including:
- a CDR1 that exhibits 100% sequence identity to SEQ ID NOs. 6 or 7;
- a CDR2 that exhibits 100% sequence identity to SEQ ID NOs. 11 or 12;
- and
- a CDR3 that exhibits 100% sequence identity to SEQ ID NOs. 16 or 17.
A single-domain antibody (sdAb) that binds to snake bungarotoxin, comprising an amino acid sequence identical to SEQ ID NO. 3.
A single-domain antibody (sdAb) that binds to snake bungarotoxin, wherein the sdAb comprises at least one single-variable region that includes a plurality of complementarity-determining regions (CDRs) including:
- a CDR1 identical to SEQ ID NO. 8;
- a CDR2 identical to SEQ ID NO. 13;
- and
- a CDR3 identical to SEQ ID NO. 18.
A single-domain antibody (sdAb) that binds to snake cobrotoxin, comprising an amino acid sequence identical to SEQ ID NO. 4.
A single-domain antibody (sdAb) that binds to snake cobrotoxin, wherein the sdAb comprises at least one single-variable region that includes a plurality of complementarity-determining regions (CDRs) including:
- a CDR1 identical to SEQ ID NO. 9;
- a CDR2 identical to SEQ ID NO. 14;
- and
- a CDR3 identical to SEQ ID NO. 19.
A single-domain antibody (sdAb) that binds to snake venom phospholipase A2 (svPLA2), comprising an amino acid sequence identical to SEQ ID NO. 5.
A single-domain antibody (sdAb) that binds to snake venom phospholipase A2 (svPLA2), wherein the sdAb comprises at least one single-variable region that includes a plurality of complementarity-determining regions (CDRs) including:
- a CDR1 identical to SEQ ID NO. 10;
- a CDR2 identical to SEQ ID NO. 15;
- and
- a CDR3 identical to SEQ ID NO. 20.
