Hemolysis-in-gel (HIG) test for antibodies to influenza A, measles and mumps using liquid nitrogen freezed erythrocytes coupled with the respective viral antigen.
A drawback with the hemolysis-in-gel test is the constant need for fresh erythrocytes which must be treated with virus before incorporation in the gel. This problem was overcome by freezing small droplets containing erythrocytes to which antigen had been attached. The droplets were stored at -70 degrees C or in liquid nitrogen. This modification was applied in detecting antibodies to influenza, measles and mumps viruses and the results were shown to equal those obtained with fresh erythrocytes.
