Antibodies of Groups One and Two, Okay?

Group one seems to recognize overlapping epitopes in the g n. Group three didn't compete with they have some other previously established ana bodies which they could use as reference. They seemed to befinding distinct epitopes in g n slash g c. And then they have group four, which would not bind uble spike. And they say, maybe this binds a tetrimer only because the soluble protein is not forming a tetrimers. So where do these annibodies bind? There's a number of ways you can do this, but one way is to select for virus mutans that are resistant to neutralization by the antibodies.
