The Anti-Plasmid is used to remove unwanted Genes from a host.
Craft an empty Anti-Plasmid with any completed regular Plasmid to get an Anti-Plasmid of the same Gene.
Put it through the Plasmid Injector the same way as a regular Plasmid, and then when it's injected into the host, it will remove the Gene from them if they have it.
