Biologically uncommon D-aspartyl (Asp) residues have been reported in proteins of the tooth, eye lens, aorta, and
brain in elderly humans. Aspartic acid is the most easily racemizable amino acid and D-Asp may be formed by
racemization in metabolically inactive tissues during the chronological aging process. We prepared a highly specific
polyclonal antibody against peptide Gly-Leu-D--Asp-Ala-Thr-Gly-Leu-D-b-Asp-Ala-Thr-Gly-Leu-D-
-Asp-Ala-Thr (anti-peptide 3R antibody) which corresponds to three repeats of positions 149-153 of human
A-crystallin. This antibody can distinguish the configuration of the Asp-residue, that is, it reacts very strongly with the
D--Asp-containing peptide but not react with the L--Asp-, L--Asp- and D--Asp-containing peptides.

Immunoreactivity of the antibody for D-b-Asp-containing peptide (peptide 3R) in the skin. Skin specimens, obtained from the sun-exposed area (face) of 9-year-old (A), 59-year-old (B), and 86-yearold (C), or sun-protected area (buttock) of 85-year-old (D), were embedded in paraffin and then immunoreacted with the antibody for peptide 3R at 1:100 dilution for 24 h. The sections were incubated with rabbit anti-Ig antibody at 1:50 dilution for 2h. Antigen-antibody complex was visualized by avidin?biotin complex (60 in A, B and D, 100 in C).
