Antibodies are glycoprotein molecules that recognize the bond to antigens, including specific proteins. They play an important role in preventing infections.

Since aggregates of such antibodies affect their function, evaluations of the physical properties of antibodies is important.

We used bovine-derived IgG to measure particle diamter and zeta potential and studied the heat transition conditions.
