General description
The Millicell® HY Flask is designed to enhance cell culture efficiency across various research applications, including cell banking, cell-based assays, and virus production.
Features and Benefits
- Multilayer Design: Available in 3- and 5-layer configurations, providing a larger surface area for cell growth while maintaining a compact footprint similar to traditional T-flasks
- Enhanced Accessibility: Designed for better pipette access, accommodating larger volume pipettes (up to 25 mL)
- Increased Efficiency: Cultivate more cells in the same space, maximizing research output
- Space Optimization: Achieves significant space savings compared to other multilayer flasks on the market
Preparation Note
- 要进行细胞播种,在Millicell HY T-1000烧瓶中加入所需的生长培养基。
- 添加所需数量的细胞以达到典型的播种密度。
- 将细胞和培养基混合,抬起烧瓶的末端,上下移液几次,直到达到均匀的悬浮。注意:未能充分将细胞混合到均匀的悬浮液中可能导致细胞在Millicell HY烧瓶各层之间分布不均匀。
- 将烧瓶侧放,使液体体积在各层烧瓶中均匀平衡。
- 倾斜烧瓶的末端,以划分每层烧瓶的液体体积。
- 放下烧瓶,使细胞悬浮液均匀地散布在每一层的整个表面。
- 根据体积的不同,可能需要摇动烧瓶的所有四个角,以确保整个表面湿润。注意:如果在润湿过程中任何一层的液体体积发生变化(例如,液体从顶层溢出到下层),重复步骤4–6以确保液体在所有层之间均匀分布。
- 当运输到培养箱时,将烧瓶放回垂直位置。将烧瓶平放于培养箱中(如第6步),在适当的条件下培养细胞。
- 如果需要交换培养基,从Millicell HY T-1000烧瓶中抽吸或倒出培养基。注意:由于Millicell烧瓶的表面积较大,每次抽吸后可能需要让烧瓶侧立几分钟,以便所有残留液体汇集到一个共同的点,以便第二次抽吸完全除去剩余液体。
- 加入适量的新鲜培养基,重复第4–8步。
- 要收获细胞,按第9步所述移除培养基。
- 向烧瓶中加入所需量的适当洗涤溶液(例如,PBS或0.02% EDTA),重复第4–7步。
- 按照第9步除去洗涤液。
- 根据首选方案添加所需量的解离酶(例如,0.25%胰蛋白酶/EDTA或等效物),重复第4–8步,并孵育。每cm2所需的解离酶体积不需要从T型烧瓶方案变化。注意:在显微镜下观察,确保所有细胞与烧瓶表面完全分离。不能使细胞与培养表面完全分离(使所有细胞自由漂浮)可能导致细胞产量降低。
- 如果使用胰蛋白酶,加入所需体积的灭活溶液,如含血清的培养基。
- 如第9步所述,通过吸气或倒吸方法收集细胞。
