Agglutination activity is expressed in mg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, of a 1 μg per mL solution. This activity is the lowest concentration to agglutinate a 2% suspension of trypsinized human blood group O erythrocytes after 1 hr at 25 °C.

ECA is not blood group specific, but has an affinity for D-galactose and D-galactosides. It is reported to be mitogenic for human peripheral blood T lymphocytes.

Purified by affinity chromatography.
