Features of TSAT:

Reactive groups: NHS ester (three ends)
Reactive towards: amino groups (primary amines)
• NHS ester couples to amines at pH 7-9 form stable amide bonds
• Trifunctional amine-reactive crosslinking agent
• Non-cleavable
• Water-insoluble (dissolve first in DMF or DMSO)

• Preparation of multicomponent aggregates
• Polyerization of protein interactions for nearest-neighbor studies
• Core molecule for the construction of dendritic polymers
