Antibodies to olanzapine haptens and use thereof
Disclosed is an antibody which binds to olanzapine, which can be used to detect olanzapine in a sample such as in a competitive immunoassay method. The antibody can be used in a lateral flow assay device for point-of-care detection of olanzapine, including multiplex detection of aripiprazole, olanzapine, quetiapine, and risperidone in a single lateral flow assay device.
1. A method of producing an antibody which binds to olanzapine, the method comprising:
selecting a host for antibody production; and
(ii) inoculating the host with a conjugate having the formula:
wherein the host produces the antibody which binds to olanzapine.
2. A method of producing a hybridoma cell line capable of producing a monoclonal antibody which binds to olanzapine, the method comprising:
(i) selecting a host for antibody production;
(ii) inoculating the host with a conjugate having the formula:
(iii) fusing a cell line from said inoculated host with a continuously dividing cell to create a fused cell capable of producing the monoclonal antibody which binds to olanzapine; and
(iv) cloning the fused cell so as to obtain a hybridoma cell line.
3. The method of claim 1 , wherein the protein is keyhole limpet hemocyanin, bovine thyroglobulin, or ovalbumin.
4. The method of claim 2 , wherein the protein is keyhole limpet hemocyanin, bovine thyroglobulin, or ovalbumin.
5. The method of claim 1 , further comprising generating an antibody binding fragment from the antibody which binds to olanzapine, wherein the antibody binding fragment is selected from the group of fragments consisting of Fv, F(ab′), F(ab′)2, scFv, minibody and diabody fragments.
6. The method of claim 1 , wherein the antibody specifically binds to olanzapine, wherein a dissociation constant of the antibody and olanzapine is less than or equal to 1 μM.
7. The method of claim 2 , wherein the hybridoma cell line is capable of producing a monoclonal antibody which specifically binds to olanzapine, wherein a dissociation constant of the monoclonal antibody and olanzapine is less than or equal to 1 μM.
