1、甲基丙烯酸酯化明胶(Methacrylated Gelalin,GelMA)是一种光敏生物材料; 2、GelMA与蓝光或紫外光引发剂配合使用,可在蓝光或紫外光作用下交联固化; 3、GelMA配制的浓度越高,固化后的硬度也越大; 4、GelMA具有好的生物相容性,可与细胞混合后进行生物3D打印。 明胶( Gelatin )是经胶原蛋白适度水解和热变性得到的天然生物高分子材料,其具有和胶原相似的氨基酸序列。明胶侧链上含有多种活性基团,如氨基、羧基、羟基等,多位点化学修饰的可能性使明胶受到众多水凝胶研究者的青睐。 甲基丙烯酰化明胶( GelMA )为双键改性明胶,其可通过紫外及可见光在光引发剂作用下交联固化成胶。 GelMA 兼具天然和合成生物材料的特征,具有适于细胞生长和分化的三维结构、优异的生物相容性和细胞反应特性,其可替代人工基底膜或其他天然胶原蛋白水凝胶。此外, GelMA 具备良好的温敏凝胶特性和可降解性,其机械性能可调,能够提供多种黏弹特性,已广泛应用于细胞 3D 培养、组织工程、生物 3D 打印等研究领域。 推出的 GelMA 产品( EFL-GM 系列)通过严格的原料筛选及品质检测,具有批次稳定、服务专业等优点。 为了更好的帮助用户选择 GelMA 型号与使用浓度,通过系统检测与分析,现给出 EFL-GM 系列水凝胶理化性能、生物相容性、 3D 打印性能参数如下: 1. Methacrylated Gelatin (GelMA) is a photocurable biomaterial; 2. GelMA can be cured with a light initiator under blue or UV light; 3. The stiffness of GelMA hydrogel is related to the concentration. The higher the concentration is, the harder the stiffiiess is after curing; 4. GelMA has good biocompatibility, it can be mixed with cells for 3D bioprinling.
