Figure 1 (IMAGE) Moscow Institute of Physics and Technology Caption An autoantibody has multiple 'hands' -- fragments that recognize targets. In the test, the antibody grabs the target immobilized on the glass surface with one hand and catches the targets passing by with the other. The process reflects what happens in the natural environment and provides quantitative information on the actual activity of antibodies in the living organism Credit Alexey Orlov et al./Biosensors and Bioelectronics Usage Restrictions None License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
