What do the provided dry antisense/PTO pellets look like?

There is a normal degree of variation in the appearance of the supplied dry pellets. Variation in appearance per se does not indicate a quality defect. In general, appearance of unmodified and dye-labeled antisense/PTO pellets may vary from powdery to hyaloid. The color of unmodified antisense/PTO pellets may range from transparent over off-white and yellowish to tan. The pellets of labeled antisense/PTO are colored according to the dye attached.
