ILEX LIFE SCIENCES LLC 3-D LIFE PEG-LINK 200 UL
3-D Life PEG-Link, non-cell-degradable thiol-modified polyethylene glycol, hydrogel crosslinker component (200 ul). INTRO: 3-D Life technology, manufactured in Germany by Cellendes GmbH, is an integrated system for generation of hydrogels used in 3D cell culture. 3-D Life represents the most flexible system for biomimetic hydrogel design. DESCRIPTION: 3-D Life PEG-Link consists of polyethylene glycol carrying a thiol at each end. When combined with the 3-D Life Hydrogel polymers, thiol groups on PEG-Link form stable thioether bonds with the thiol-reactive groups on the polymers, resulting in formation of the hydrogel. PEG-Link can be used with 3-D Life functionalized polymers Mal-PVA, Mal-Dextran, SG-PVA and SG-Dextran. APPLICATION: 3-D Life PEG-Link is used together with thiol-reactive polymers of the 3-D Life system to establish 3-D cell cultures. QUANTITY: When used with polymers of the 3-D Life Hydrogel system up to 2 ml hydrogel can be generated, depending on gel stiffness.

DMG-PEG 2000 is utilized in the preparation of liposomes for siRNA delivery, enhancing transfection efficiency in vitro. It is also employed for lipid nanoparticles in an oral plasmid DNA delivery approach in vivo, through surface modification, to improve mucus permeability and delivery efficiency of the nanoparticles.
- Used for liposome preparation for siRNA delivery with improved transfection efficiency in vitro.
- Used for lipid nanoparticles for oral plasmid DNA delivery with improved mucus permeability and delivery efficiency in vivo.
Medchemexpress LLC Mal-PEG5-NHS ester | 1807537-42-3 | 99.0% | 10 MG
Mal-PEG5-NHS ester is an Alkyl/ether and PEG-based PROTAC linker. It is used in the synthesis of PROTACs, which are composed of two different ligands connected by a linker. One ligand is for an E3 ubiquitin ligase and the other is for the target protein. PROTACs function by exploiting the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- Alkyl/ether and PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Exploits ubiquitin-proteasome system
- Selectively degrades target proteins
