PEGDA(聚乙二醇（二醇）二丙烯酸酯)

PEGDA [Poly(ethylene glycol) diacrylate]聚乙二醇（二醇）二丙烯酸酯

Polyethylene (glycol) Diacrylate (PEGDA) is a blank slate hydrogel that gels rapidly at room temperature in the presence of a photo-initiator and UV light. They are hydrophilic, elastic and can be customized to include a variety of biological molecules.
聚乙二醇（二醇）二丙烯酸酯（PEGDA）是一种空白板岩水凝胶，在光引发剂和紫外光的存在下在室温下快速凝胶化。它们是亲水的，有弹性的，并且可以定制以包括各种生物分子。

Polyethylene (glycol) Diacrylate (PEGDA) hydrogels are powerful tools for uncovering basic cellular biology because they are considered biologically inert (“blank slate”) and their mechanical properties can be varied over a large range of moduli. PEGDA is an emerging scaffold for tissue engineering and regenerative medicine since polymerization can occur rapidly at room temperature and requires low energy input, has high water content, is elastic, and can be customized to include a variety of biological molecules. PEGDA is a crosslinker repeating polymer crosslinker. >95% acrylated. Can be used as a thiol-reactive crosslinker in our HyStem systems at low concentration, or can be used to make a PEGDA-only hydrogel in the presence of a free-radical chain photoinitiator and a UV light source. PEG-only gels do not typically support cell attachment without the incorporation of cellular attachment sites.
聚乙二醇（乙二醇）二丙烯酸酯（PEGDA）水凝胶是揭示基本细胞生物学的有力工具，因为它们被认为是生物惰性的（“空白板岩”），并且它们的机械性质可以在大范围的模量上变化。PEGDA是用于组织工程和再生医学的新兴支架，因为聚合可以在室温下快速发生并且需要低能量输入，具有高含水量，具有弹性，并且可以定制为包括多种生物分子。PEGDA是交联剂重复聚合物交联剂。> 95％丙烯酸酯。可以在我们的HyStem系统中以低浓度用作硫醇反应性交联剂，或者可以在自由基链光引发剂和UV光源的存在下用于制备仅PEGDA的水凝胶。
