Advanced Biomatrix Extralink PEGDA Thiol-reactive crosslinker for HyStem-C and HyStem-HP, 10 units x 0.5 mL
Extralink PEGDA is a thiol-reactive crosslinker designed for use in HyStem-C and HyStem-HP kits. Pack comes with Buffer B. HyStem V2.0 kit components are reconstituted with a buffered 1X PBS. The resulting components will also result in a pH neutral isotonic salt hydrogel. The ending pH, osmo, and rheological properties are the same from Version 1.0 to Version 2.0. Extralink is polyethylene diacrylate (PEGDA) with a molecular weight of 3500 Da. It is a thiol-reactive crosslinker that covalently reacts with the thiol groups in Glycosil, Heprasil and Gelin-S to form viscoelastic hydrogels. Extralink vials are >80% acrylated and supplied as the crosslinking component in all HyStem hydrogel kits. Extralink vials are paired with HyStem-C and HyStem–HP kits while Extralink-Lite vials are paired with HyStem hydrogel kits to provide comparable experiences despite the different HA concentrations.
Medchemexpress LLC 6-FAM-PEG3-azide | 412319-45-0 | 98.1% | C29H28N4O9 | 10MG
6-FAM-PEG3-Azide is a fluorescent labeling reagent composed of a 6-carboxyfluorescein (6-FAM) dye linked to an azide via a PEG3 spacer. It is designed for covalent conjugation to alkyne-functionalized partners using copper-catalyzed azide-alkyne cycloaddition (CuAAC) or strain-promoted azide-alkyne cycloaddition (SPAAC), enabling fluorescent labeling of oligonucleotides and other biomolecules.
- Fluorescent labeling with excitation 498 nm and emission 532 nm.
- PEG3 spacer improves water solubility and reduces steric hindrance.
- Azide functional group for CuAAC and SPAAC click chemistry.
- Solid, light yellow to yellow form stable when stored as powder at -20°C.
- High purity (~98.1%) suitable for analytical and labeling applications.
