OPSS-PEG-SCM is a linear heterobifunctional PEG reagent with OPSS group and NHS ester at both ends of the molecular chain. OPSS stands for o-pyridinyl disulfide or o-pyridinyl disulfide, https://peg.bocsci.com/catcs/1077/opss-peg-scm/

OPSS-PEG-NH2 has an ortho-pyridyl disulfide and an amine group at both ends of the chain, respectively. It is a thiol (-SH) group reactive PEG derivative that can be used to modify biomolecules or other materials by its available mercaptan groups. https://peg.bocsci.com/catcs/1082/opss-peg-nh2/

N-hydroxysuccinimide-polyethylene glycol-N-hydroxysuccinimide (NHS-PEG-NHS) is a double PEG derivative with two N-hydroxysuccinimide groups. It is usually a viscous liquid or solid powder, depending on the molecular weight. https://peg.bocsci.com/catcs/1092/nhs-peg-nhs/

NH2-PEG-(γ)PGA (amino-polyethylene glycol-poly-L-glutamic acid) is a linear amphiphilic block copolymer with poly-L-glutamate as hydrophobic part and amino group functionalized PEG as hydrophilic part. https://peg.bocsci.com/catcs/1....004/nh2-peg-%ce%b3pg
