AGGLUTINATION (FOR MEDICAL & CLINICAL CHEMISTRY STUDENTS)
¾®¶°§@¥Î¡]Âå¾Ç¤ÎÁ{§É¤Æ¾Ç¾Ç¥Í¾A¥Î¡^
Agglutination of particles by antibodies is an extremely versatile technique for detecting and quantitating both antigens and antibodies. This videotape explains the basic process of agglutination using clear, simple graphics and then goes on to show examples of the procedures being used in the laboratory. The second version (for medical and clinical chemistry students? also includes a detailed explanation and demonstration of the detection of rheumatoid factor by sheep red cell agglutination. Level: Laboratory technicians, undergraduate or master, some knowledge of biology and immunology is assumed.
