NH2-PEG-NH2 is a homobibifunctional PEG derivative. It has a linear bifunctional PEG crosslinker with active primary amine or NH2 groups, which can react quickly with activated carboxylic acid or carboxyl groups such as NHS esters to form stable amide bonds.

NH2-PEG-NH2 Amine PEG12 Amine, monodisperse Synonyms: Polyethylene glycol; Linear Formula: NH2(CH2CH2O)11CH2CH2NH2 at Sigma-Aldrich

8arm-PEG40K average MN 40,000, NH2, hexaglycerol core, HCl Salt, carboxyl reactive Synonyms: 8arm-PEG-NH2,Polyethylene glycol; Linear Formula: R(O(CH2CH2O)nCH2CH2NH2)8 at Sigma-Aldrich

PEG NHS ester is an amine reactive PEG reagent that is widely used in bioconjugation with antibodies (ADC), protein, peptide & other molecules. The NHS ester group can react with primary amines (NH2) on the macromolecule very readily at pH …

AxisPharm’s Amine-PEG products offer defined PEG lengths for precise tuning of the distance between ADC mAbs and payloads. The high-purity PEG-NH2 reagents come in various linker lengths, with custom options available.

HS-PEG-NH2 is a linear heterobifunctional PEGylation reagent with a thiol and an amine. It is a useful crosslinking or bioconjugation reagent with a PEG spacer. Thiol, or SH, sulfhydryl, or mercapto group selectively reacts with maleimide, OPSS, vinylsulfone and transition metal surface including gold, silver, etc.

8-Arm PEG-Amine is a multiarm PEG derivative with amine groups at each terminal of the eight arms connected to one hexaglycerol core. The reactive primary amine or NH2 group can rapidly react with activated carboxyl acid such as NHS ester to form stable amide bonds.

DSPE-PEG-NH2 (DSPE-PEG-Amine), MW 2K is a linear heterobifunctional PEGylation reagent containing DSPE phospholipids and amines. It can modify liposome surfaces with biomolecules with amine-reactive groups (NHS, thiolates).

4-Arm PEG-Amine (4-arm PEG-NH2) is a multiarm PEG derivative with amine groups at each terminal of the four arms connected to one pentaerythritol core. The reactive primary amine or NH2 group can rapidly react with activated carboxyl …

DSPE-PEG-NH2 is a linear heterobifunctional PEGylation reagent with a DSPE phospholipid and an amine. It is a useful self-assembling reagent to prepare PEGylated liposome or micelle while also providing an amine group for bioconjugation.
