产品介绍
1. 甲基丙烯酸酯化硫酸软骨素 (Chondroitin Sulfate Methacryloyl,CSMA) 是一种光敏生物材料; 2. CSMA 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. CSMA 配制的浓度越高,固化后的硬度也越大; 4. CSMA 具有良好的生物相容性,可与细胞混合后进行生物3D打印。 硫酸软骨素(Chondroitin Sulfate,ChS)是一种硫酸化的糖胺聚糖,其分子链由交替的1,4-连接的N-乙酰-β-D-半乳糖胺(β-D-GalNAc)和1,3-连接的β-D-葡萄糖醛酸(β-D-GlcA)二糖单元组成。作为人体内广泛分布的糖胺聚糖和软骨及细胞外基质的重要部分,ChS大量存在于皮肤、软骨、肌腱、心脏瓣膜和中枢神经系统等组织中,在体内发挥着重要的生理作用,如参与骨和软骨的形成、调控生长因子(成纤维细胞生长因子和转化生长因子-β等)、促伤口愈合、抗炎、抗凝血、抗氧化以及抗肿瘤等。 甲基丙烯酰化硫酸软骨素 (Chondroitin Sulfate Methacryloyl,CSMA) 是通过在硫酸软骨素分子链上引入甲基丙烯基团进而赋予其光固化能力。由于便携的交联成型方式和良好的生物相容性,基于ChSMA的材料体系已被广泛应用于许多生物医药研究领域,包括:骨关节炎治疗、关节软骨修复、颅骨修复等。ChS分子上富含易于修饰改性的羧基和羟基,其可用于构建多种生物材料,如用于肿瘤的诊断和治疗的纳米药物载体以及生物粘合剂等。 使用方法: 1. 在无菌条件下,配制 5%-10% 的CSMA 溶液;用0.22 µm滤膜过滤除菌; 2. 与细胞和蓝光引发剂LAP混合,置入蓝光生物3D打印机的墨盒; 3. 三维打印,蓝光固化 质控检验: 每一批次的 CSMA 均经 1H NMR, HPLC和细胞学检测,证实其化学结构, 取代度25-35%,无细胞毒性; CSMA 配制的水凝胶, 加入蓝光引发剂LAP后,可在蓝光作用下迅速固化。
