PROCESS AND DEVICE FOR MEASURING ANTIGEN-ANTIBODY REACTIONS

摘要

Antigen-antibody reactions are measured by passing laser light through the mixture of the antigen solution with the corresponding antibody and measuring the light scattered in the forward direction and determining its intensity. The device used comprises a measuring system consisting of a laser, at least two diaphragms, a system of lenses and a photodetector and a light trap having a diameter corresponding to 1.1 to 1.7 times the diameter of the laser beam.
