I. [Product Description]
OVA-PEG-Tosyl (Tosylate) is a high-purity protein-polyethylene glycol conjugate that combines the biocompatibility of ovalbumin with the spatial modification properties of PEG. It can be used as an organic intermediate for bioconjugation reactions or as a functionalized carrier in the synthesis of pharmaceutical intermediates. The tosylate group endows it with excellent selective reaction activity and is suitable for directional modification in catalytic systems.
