The physics and chemistry would be identical, except for the charge having opposite sign. They would move opposite in response to electromagnetic fields, but the difference should be only in direction. Yes, the main response between matter and antimatter is annihilation, but at the particle level, a collision between a proton and an antiproton could compare to electron capture of a proton. Antimatter is rather scarce and expensive to synthesize. You'd need to use your imagination to try to figure out ways you could test for something using antimatter that you couldn't test more simply and cheaply by other means. But since it's fiction, you need not be completely constrained by physical reality. You might even conjure up a property like anti-spin. Annihilation probably wouldn't gain you much over use of antimatter, so consider whether Pauli Exclusion might allow coexistence of not just a pair of opposite spin electrons, but also a quad of opposite spin and opposite anti-spin electrons. You could double the density of matter. Watch for the reference, due to be published in March 2009.
