Figure 3From: Antibodies against the CB10 fragment of type II collagen in rheumatoid arthritisCircular dichroism (CD) spectroscopy of CB10. (a) CD analysis of CB10 (bold) showing positive ellipticity peak at 220–225 nm that was lost after heat denaturation (non-bold). (b) Thermal melting profile of CB10 followed at 222 nm. At about 20°C, unfolding of CB10 started.Back to article page
