Measurements of large circles are more accurate than are those of small circles. In which subject field? By using this site, you agree to the Terms of Use and Privacy Policy.

For most antigens, the area and the square of the diameter of the circle at the circle’s end point are directly proportional to the quantity of antigen and are inversely proportional to the concentration of antibody.
