Location of antibodies in the corneal lens of a young adult showing the distribution of antibodies within each of the three main regions. The number of pluses was determined by eye to depict relative abundance of gold particles from a single antibody. For several antibodies, the distinction between dark and light laminae in the narrow laminar region was not obvious. The Figure numbers are on the right. Names of members of the CPR family are green for RR-1 group, brown for RR-2, and blue for unclassified.
