Psophocarpus tetragonolobus (Winged bean) Lectin (PTL/PTA I- Galactose) – Cy5
Purified PTA I is conjugated to cyanine 5 (Cy5) fluorescent dye. Cyanine dyes are better able to withstand the harsh dehydration and embedding conditions required for mounting sections in non-polar plastic media, and are brighter in a non-polar environment than in an aqueous medium. Advantages of plastic over aqueous mounting media are brightness, contrast, and longevity of the fluorescence. Cy5 has an approximate peak excitation wavelength of 650 nm and an emission wavelength at 670 nm. This product comes in a stabilized liquid form.
+2° to +8° C.
