You can prepare antibody-oligo conjugates in larger quantities. I would recommend buying multiple Ab-oligo kits (we have volume discounts), because they are much easier to use than any alternative. Alternatively, you can use the more general protein-oligo kit, which can conjugate mg amounts amount of antibody. But, this kit does not contain the unique purification step that comes in the Ab-oligo kit, and requires HPLC purification of the final antibody-oligo conjugate.
