产品介绍
分子量: 380-500 kDa 物理外观: 海绵状 Sponge 注意:溶液反复冻融会影响产品性能,尽量现配现用。 甲基丙烯酰化葡聚糖(DexMA)为双键改性葡聚糖,其可通过紫外及可见光在光引发剂作用下交联固化成胶。由于DexMA具有优异的水溶性和良好的生物安全性,且抗非特异性蛋白吸附,基于DexMA的材料体系已被广泛应用于生物医学领域,如减少血管中血栓的形成、降低血液黏度和药物递送等。 产品应用 细胞三维培养、生物3D打印、组织工程等。 溶液配制 1.配制0.25% (w/v) 引发剂标准溶液 (1) 取20ml PBS,加入装有引发剂LAP的棕色瓶中(内含0.05gLAP); (2) 以40-50℃水浴加热溶解15分钟,期间振荡数次。 该LAP标准液在4°C避光条件下可保存12个月。 2.配制DexMA溶液(建议DexMA浓度为5-15%(w/v)) (1) 取所需质量的DexMA放入离心管。 (2) 取引发剂标准溶液加入到上述离心管中。 (3) 室温避光溶解30分钟,期间振荡数次。 (4) 将DexMA溶液使用0.22μm无菌针头过滤器灭菌。 二维细胞培养建议 (1) 将DexMA溶液注入孔板;(96孔板:50~100μL/孔,48孔板:100~300μL/孔,24孔板:300~500μL/孔) (2) 405nm光源,照射10-30秒使凝胶化,可通过光照时间及浓度调控凝胶强度; (3) 将培养基加入孔中覆盖凝胶,置于37℃培养箱中5分钟,清洗样品,吸去培养基; (4) 将细胞悬浮液加入到孔板中即可。根据实验设计进行培养基更换、观察拍照等操作(操作程序无特殊要求)。 三维细胞培养建议 说明:DexMA水凝胶无细胞粘附位点,如需细胞在水凝胶表面粘附,建议选择aladdin的丙烯酰化RGD肽进行修饰,修饰方式详见丙烯酰化RGD肽使用说明书。 (1) 收集细胞沉淀并用DexMA溶液重悬,配制细胞悬液; (2) 向孔板中加入细胞悬液;(96孔板:50~100μL/孔,48孔板:100~300μL/孔,24孔板:300~500μL/孔) (3) 405nm光源,照射10-30秒使凝胶化,可通过光照时间及浓度调控凝胶强度; (4) 向各孔加入培养基,于37℃培养箱中5分钟,清洗样品,移去培养基; (5) 加入新鲜培养基并长期培养。根据实验设计进行培养基更换、观察拍照等操作(操作程序无特殊要求)。 生物学性能
