- * Antigen - is a protein or subunit part of a pathogen that sparks an adaptive immune response
- * Epitopes (antigenic determinants) - are the specific sites on an antigen reacts with. THERE ARE MANY in ONE ANTIGEN
- * Hapten - too small to be antigens, needs to bind to a carrier.
- *antibodies - protein, also called (Immunoglobulins - Ig)
