Product Description

Affinity-purified Amaranthus caudatus (ACL) (SKU: 21510158) is a dimer glycoprotein made up of two subunits. ACL has preferential specificity to oliogsacharrides containing the galactosyl disacharride Galβ3GalNAc. ACL tolerates sialic acid substitution at the 3 position of galactose in the "T" antigen. It does not have specificity for blood groups but does have a higher affinity for type O erythrocytes over B and A.

ACL is labeled with fluorescein isothiocyanate (FITC) and has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. FITC conjugates have been used in a variety of immunohistochemical and flow cytometry applications. Fluorescein conjugates display a high rate of photobleaching, signal is sensitive to pH changes, broad fluorescence emission spectrum, and fluorescence quenching on conjugation to biopolymers. This product comes in a stabilized liquid form.
