Musa paradiso lectin is a glucose/mannose-specific lectin isolated from bananas. BanLec is a dimeric protein consisting of two identical 15 kDa subunits, composed of 141 amino acid residues, and has an isoelectric pH of 7.3. Depending on its crystal structure, this lectin exhibits some unusual binding properties, as it can recognize the 1,3 sugar units at the end of the reduction and the α-1, 3-linked glucose residues inside. The study also showed that BanLec has two major carbohydrate binding sites per subunit. Geranium lectins are labeled with tetramethyl rhodamine isothiocyanate (TRITC) and combined with appropriate amounts of fluorescent dyes to provide the best staining properties for this lectins. TRITC is a bright orange or red fluorescent dye whose excitation is well suited to the 532nm laser line. Tritc-labeled Banlec can be used for cell imaging applications.
