Amino PEG(PEG Amine) linkers contain an amino group on one end of the peg spacer. PEG-NH2 can easily couple with acids, acyl chloride, NHS esters, or PFP esters. As a result, the crosslinkers have been widely used for labeling, bioconjugation, chemical modification, and surface applications.

The PEG spacer in the middle enhances the aqueous solubility of the crosslinker. AxisPharm’s mono-dispersed amine PEG linkers have defined PEG length. Functionalized amine reagents are ideal tools for fine tuning the distance between ADC mAb and payload.

Axispharm offers a range of high purity PEG-NH2 reagents with different linker lengths.Different kinds of PEG Reagents may be available by custom synthesis. Fast shipping.
