One of the key advantages of PolyPEG® is its low intrinsic viscosity so that even very large PolyPEGs® of 100 kDa have low viscosity. This is particularly beneficial for biological therapeutics that have high dose requirements and avoids the need for large bore needles allowing convenience and ease of administration.
