Lectins are derived from the extracts of plants, animals, viruses and microorganisms and are known to agglutinate red blood cells. These agglutinins can select cell types according to blood group activities utilizing sugar-binding mechanisms.

Lectins form precipitates with glycoconjugates and are useful for identifying or separating oligosaccharides with identical sugar compositions such as galactose, mannose or glucose.

Carbohydrate Specificity: alpha-galactose

Inhibitory Carbohydrate: alpha-galactose

Activity: Less than 0.5ug/ml will agglutinate neuraminidase treated human erythrocytes.

Chemical Used for Conjugation: TRITC

Please do not use Phosphate Buffer Saline that causes precipitation.
