Amaranthus caudatus Lectin (ACL/ACA) - TRITC (Rhodamine)
Price: Regular price $0.00
Product Description
Affinity-purified Amaranthus caudatus Lectin (ACL/ACA) is a dimeric glycoprotein composed of two subunits. It preferentially binds to oligosaccharides containing the galactosyl disaccharide Galβ3GalNAc and can tolerate sialic acid substitutions at the 3 positions of galactose in the "T" antigen. While ACL does not exhibit specificity for blood groups, it shows a higher affinity for type O erythrocytes compared to types A and B.
Amaranthus caudatus Lectin (ACL/ACA) is conjugated with tetramethylrhodamine isothiocyanate (TRITC) to enhance its staining characteristics. TRITC is a bright orange-red fluorescent dye, optimal for excitation at the 532-nm laser line. This TRITC-labeled ACL/ACA is suitable for cellular imaging applications.
Recommended Usage: Recommended dilution 0.5 – 10 µg/ml in 1XPBS. Agglutinate human, goat, sheep, and rabbit erythrocytes (1 – 10 µg /ml).
