I 简介

I型鼠尾胶原是重要的细胞外基质,可促进细胞贴壁、维持细胞分化状态。我们的产品是从SD大鼠尾腱中提取分离,在万级实验室中经过多道工序提纯获得的,保持了胶原蛋白的生物活性。经测试,本产品pH调至中性后可成胶,可用于多种原代细胞的细胞培养,例如肝细胞、血管内皮细胞、间充质干细胞、胰岛beta等细胞。






II 试剂与耗材

—胶原母液(本产品Cat: LV-collagen003)               

—超纯水

—醋酸母液

0.22μm滤膜及50mL一次性注射器                                             

—氢氧化钠(Sigma CatS5881-500G

—移液枪及枪头

—培养板//

—生物安全柜

37/5%CO2培养箱


III 包被步骤

1. 在生物安全柜中 ,将5mL 醋酸母液加入到1L无菌水中配制成为醋酸工作液。

2. 加入I型鼠尾胶原母液,使终浓度为50μg/mL,即每100 mL醋酸工作液加入5 mg胶原蛋白(对应胶原母液体积为V=5mg/10mg/mL=0.5mL),4℃保存待用(不超过3个月)。

3. 将胶原工作液以大于/等于5μg/cm2的包被量加入到需要包被处理的培养板//瓶中,通常情况下,加入工作液为推荐培养基(见附表)使用体积的60%,如12孔板的培养基推荐使用体积为1 mL,加入0.6 mL胶原工作液即可达到饱和。

4. 生物安全柜中,常温孵育1h。延长包被时间至3小时,对后续细胞培养没有影响。

5. 将胶原工作液吸出,生物安全柜中自然晾干,封口膜封口,4℃保存不超过6个月。

6. 接种细胞前,胶原包被培养板//瓶需PBS或培养基清洗一次,以去除残留的醋酸。


IV 成胶步骤

1. 准备1M NaOH10×PBS10×DMEM以及超纯水,过滤除菌后于冰上预冷。

2. 成胶溶液的各成分添加量与配置方法:

2.1  10×PBS10×DMEM的添加量为最终体积的1/10mL

2.2  胶原添加量为:

终体积×胶原终浓度(mg/ml

=胶原添加量(mL

胶原母液浓度(10mg/mL

2.3  NaOH添加量为:

胶原添加量×0.015μL=1M NaOH添加量(μL

2.4  灭菌水的添加量:

终体积-胶原添加体积-NaOH添加体积-10×PBS10×DMEM体积=超纯水添加量(mL

3. 10×PBS10×DMEMNaOH溶液以及超纯水混合均匀至于冰上。

4. 将胶原加入混合液中充分混匀,然后立即使用。

5. 使用时可根据实验需求直接铺板,放入37℃孵育30min待胶凝固即可使用.
