Vicia villosa Lectin (VVL/VVA) 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 VVL/VVA can be used for cellular imaging applications.||Source:|Hairy vetch||Blood Specificity:|Tn Antigen||Sugar Specificity:|N-Acetylgalactosamine||Inhibitory Carbohydrate:|N-Acetylgalactosamine||Fluorescence:|Orange||Divalent Ions:|Ca++, Mn++||Excitation:|545-555nm||Emission:|570-580nm||Storage and Stability:|May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C.
