Antigen: Any foreign substance(like- toxins,proteins,etc) interact with the immuno system and stimulate the production of antibody is called antigen.

Non-pathogenic: It is a property of any substance which means that the substance is harmless,or it is not able to infect us or can not cause any disease.

Now some exmaple of these non-pathogenic antiges are-

  1. H antigen: It is found in the blood which stimulates the production of antigen A & B in the RBC.
  2. Proteins,Peptides,Lipids & Polysaccharide: These are also a type of antigen and they bind with the antigen-specific receptors but does not excites the immuno system.
  3. Protein bound drugs: The protein bound drugs which is also a type of antigen but it is not a pathogen it helps to prevent disease.
