R-MU-007	4arm-PEG-NPC	4 arm-Polyethylene glycol-Nitrophenyl Carbonates,4 arm-PEG-NPC,NPC-PEG-4 arm from ruixi 4 arm polyethylene glycol- NPC is a multi-arm polyethylene glycol derivative with NPC at each end of the four arms connected to a pentaerythritol nucleus.4 arm-peg2000-NPC,4 arm-peg5000-NPC and so on.	price>
R-MU-008	4arm-PEG-SAS	4 arm-Polyethylene glycol-Succinimidyl Amido Succinate,4 arm-PEG-SAS ,SAS-PEG-4 arm from ruixi armester groups at each terminal of the four arms connected to one pentaerythritol core. PEG-SAS (succinimidyl succinamide ester) is one type of PEG-NHS reagents. There is a C2 hydrocarbon amide linkage between PEG and the NHS ester.	price>
R-MU-009	4arm-PEG-SC	4 arm-Polyethylene glycol-Succinimidyl Carbonate,4 arm-PEG-SC,SC-PEG-4 arm from ruixi 4-arm polyethylene glycol- SC is a multi-arm polyethylene glycol derivative with SC at each end of the four arms connected to a pentaerythritol nucleus.4 arm-peg2000-SC,4 arm-peg5000-SC and so on.	price>
R-MU-0010	4arm-PEG-SCM	4 arm-Polyethylene glycol-Succinimidyl Carboxymethyl estere，4 arm-PEG-SCM，SCM-PEG-4 arm from ruixi Ruiixibiotech offer 4 arm PEG Succinimidyl Carboxymethyl Ester (4-arm PEG-SCM) derivatives which can be cross-linked into PEG hydrogels. PEG hydrogels have a variety of applications in medical devices and regenerative medicine, and are especially of interest for controlled drug release. Nanosoft Polymers’ 4 arm PEGs are synthesized by ethoxylation of pentaerythritol (4ARM PEG).	price>
R-1805-X	4 arm-PEG-SG	4 arm-Polyethylene glycol-succinimidyl glutarate ,4 arm-PEG-SG,SG-PEG-4 arm from ruixi 4-arm Poly(ethylene glycol) succinimidyl glutarate (4-Arm PEG-SG) from ruixibiotech are high quality multi-arm PEG derivatives with succinimidyl ester at each terminal of the four arms that can quickly react with primary amine. The total molecular weight of 4-Arm PEGs is the sum of the molecular weights of all four arms.	price>
R-MU-0011	4arm-PEG-SS	4 arm-Polyethylene glycol-Succinimidyl Succinate,4 arm-PEG-SS,SS-PEG-4 arm from ruixi 4-arm PEG succinimidyl succinate ester (4-arm PEG-SS) is a multiarm PEG derivative with succinimidyl NHS active ester groups at each terminal of the 4 arms connected to onepentaerythritol core. PEG-SS (succinimidyl succinate ester) is one type of PEG-NHS reagents. There is a C2 hydrocarbon ester linkage between PEG and the NHS ester. NHS is a good leaving group which can react with amine-containing moities.	price>
R-MU-0012	4arm-PEG-SVA	4 arm-Polyethylene glycol-Succinimidyl Valerate,4 arm-PEG-SVA,SVA-PEG-4 arm from ruixi 4-arm polyethylene glycol- SVA is a multi-arm polyethylene glycol derivative with SVA at each end of the four arms connected to a pentaerythritol nucleus.4 arm-peg2000-SVA,4 arm-peg5000-SVA and so on.	price>
R-MU-0013	4arm-PEG-Epoxides	4 arm-Polyethylene glycol-Epoxides,4 arm-PEG-Epoxides,Epoxides-PEG-4 arm from ruixi 4-Arm PEG-Epoxide is a multiarm PEG derivative with epoxide or epoxy groups at each terminal of the four arms connected to one pentaerythritol core.Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1-(O-CH2-CH2)n-O-R2. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation.	price>
R-MU-0014	4arm-PEG-VA	4 arm-Polyethylene glycol-Valeric Acids, 4 arm-PEG-VA, VA-PEG- 4 arm from ruixi 4-arm polyethylene glycol- VA is a multi-arm polyethylene glycol derivative with VA at each end of the four arms connected to a pentaerythritol nucleus.4 arm-peg2000-VA,4 arm-peg5000-VA and so on.The valeric acid carboxylate of d-biotin may be activated to an NHS ester for direct modification of amine groups in proteins and other molecules. NHS esters react by nucleophilic attack of an amine on the carbonyl group, releasing the NHS group and forming a stable amide linkage.	price>
