Circular dichroism refers to the difference in absorption of left and right circularly polarized light. Classical application of CD is quantitation of the protein secondary structure. Each of the secondary structure types possesses its own characteristic CD spectrum. The CD spectrum of protein under study is deconvoluted into the components corresponding to contributions from different structure types. Since antibodies are characterized by very high content of β-pleated structure, their CD spectra closely resemble those for pure β-strands (Fig. 3).
