General description

O,O′-Bis[2-(N-Succinimidyl-succinylamino)ethyl]polyethylene glycol (NHS-PEG-NHS) is a cross-linking reagent.

Application

O,O′-Bis[2-(N-Succinimidyl-succinylamino)ethyl]polyethylene glycol (NHS-PEG-NHS) is suitable reagent used in the covalent conjugation of peanut agglutinin and anticarcinoembryonic antigen antibodies (αCEA) tumor-targeting ligands to near-infrared (NIR)fluorescent superparamagnetic iron oxide (IO)- human serum albumin (HSA) nanoparticles. It is suitable reagent used in the synthesis of novel series of mesoporous silica nanoparticles with different pore sizes, useful for high loading and controlled release of short oligonucleotides.
