Description

Analysis Note

Agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 7.3, of a 1 mg/ml solution. This activity is the lowest concentration to agglutinate a 2% suspension of human erythrocytes after 1 hour incubation at 25 °C.

Biochem/physiol Actions

LEA is not blood group specific, but has an affinity for N-acetyl-β-D-glucosamine oligomers. The lectin is a glycoprotein containing approx. equal amounts of protein and carbohydrate and is reported to inhibit the mitogenic activity of phytohemagglutinin from Phaseolus vulgaris. This lectin binds endothelial cells and is used to visualize the microvasculature.

Preparation Note

Purified by affinity chromatography.
