Musa paradisiaca lectin is a glucose/mannose-specific lectin (BanLec) isolated from banana. BanLec is a dimeric protein that consists of two identical 15 kDa subunits, composed of 141 amino acid residues, and has an isoelectric point of pH 7.3. Based on its crystal structure, this lectin exhibits some uncommon binding properties, as it recognizes 1,3-sugar units at the reducing termini and the internal α-1,3-linked glucosyl residues. Studies have also shown that BanLec has two primary carbohydrate binding sites per subunit. Musa paradisiaca lectin is labeled with tetramethylrhodamine isothiocyanate (TRITC) and has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. TRITC is a bright orange or red-fluorescent dye with excitation ideally suited to the 532-nm laser line. TRITC labeled Banlec can be used for cellular imaging applications.
