细胞分选柱是一种用于有柱细胞分选的专用耗材,专为温和分离经纳米磁珠标记的细胞而开发。由于细胞分选纳米磁珠体积极小(粒径:50-100 nm),需要高强度磁场才能磁吸已标记的细胞,细胞分选柱内置经优化的基质,与磁力分选系统配套使用时,可将磁场扩大近万倍,实现磁性标记细胞的高效捕获与温和洗脱,广泛用于科研及临床前阶段的细胞富集、去除和分选。
| 货号 | 产品名称 | 标记细胞最大载量 | 总细胞最大载量 |
| M1520097 | MS细胞分选柱 | 1× 10⁷ | 2× 10⁸ |
| L1520103 | LS细胞分选柱 | 1× 10⁸ | 2× 10⁹ |
注:当分离的细胞比淋巴细胞大时,分选柱容量可能会降低。
操作步骤
1. 分选柱准备
(1) 安装分选柱:将分选柱插入到合适的磁力架中,确保柱翼朝前,在分选柱流出位置放置收集管。
(2) 润洗分选柱:向分选柱中加入500 μL的分选缓冲液,让缓冲液自然流过分选柱。
(3) 丢弃流出液:更换收集管,分选柱准备完成。
2. 磁性分离
磁性分离前需进行磁性标记,具体磁性标记方法参照细胞分选纳米磁珠的说明书。
(1) 细胞悬液准备:将细胞重悬于分选缓冲液,每10⁷个细胞用50 μL分选缓冲液重悬。
注:对于更高的细胞数量,可相应的扩大缓冲液体积。
(2) 上样:将细胞悬液加入准备好的分选柱中,收集含有未标记细胞的流出液。
(3) 洗涤:用500 μL分选缓冲液洗涤分选柱3次。收集通过的未标记细胞,并与步骤 (2) 的流出液混合。
注:一旦分选柱储液器空,就立即加入等量的缓冲液进行清洗步骤。
(4) 取下分选柱,将分选柱放置在新的收集管上。
(5) 洗脱:向分选柱中加入1 mL分选缓冲液,使用随附的活塞快速将磁性标记的细胞洗脱出来。
注:(可选)为了提高磁性标记细胞的纯度,可以将洗脱的细胞通过第二根MS细胞分选柱进行再次分选。
注意事项
1. MS细胞分选柱及配套柱塞,每个独立无菌包装,属于一次性耗材,不建议重复使用。
2. 实验前配置分选缓冲液:PBS (pH 7.2), 0.5% BSA, 溶解2mM EDTA,充分混匀,置于4℃保存。
3. 由于样本的差异和研究目的不同,最佳的实验条件需要客户自行摸索。
4. 本产品仅供科研用途。
5. 为了您的安全和健康,请穿实验服并戴一次性手套操作。
Cell separation column is a specialized consumable designed for column-based cell sorting, developed specifically for the gentle isolation of cells labeled with nanomagnetic beads. Due to the extremely small size of the cell separation nanomagnetic beads (particle size: 50–100 nm), a high-intensity magnetic field is required to attract the labeled cells. The column contains an optimized matrix that, when used with a magnetic separation system, amplifies the magnetic field nearly ten-thousand-fold, enabling efficient capture and gentle elution of magnetically labeled cells. It is widely used for cell enrichment, depletion, and sorting in research and preclinical stages.
| Cat. No. | Product Name | Max. Load of Labeled Cells | Max. Total Cell Load |
| M1520097 | MS Columns | 1× 10⁷ | 2× 10⁸ |
| L1520103 | LS Columns | 1× 10⁸ | 2× 10⁹ |
Note: When isolating cells larger than lymphocytes, the column capacity may be reduced.
Procedure
1. Column Preparation
(1) Column installation: Insert the separation column into a suitable magnetic stand, ensuring the column wings face forward. Place a collection tube at the column outlet.
(2) Column priming: Add 500 μL of separation buffer to the column and allow it to flow through naturally.
(3) Discard flow-through: Replace the collection tube. The column is now ready.
2. Magnetic Separation
Magnetic labeling must be performed before magnetic separation. Refer to the nanomagnetic bead instructions for specific labeling methods.
(1) Cell suspension preparation: Resuspend cells in separation buffer, using 50 μL of buffer per 10⁷ cells.
Note: For higher cell numbers, increase the buffer volume accordingly.
(2) Sample loading: Apply the cell suspension to the prepared column. Collect the flow-through containing unlabeled cells.
(3) Washing: Wash the column three times with 500 μL of separation buffer. Collect the unlabeled cells that pass through and combine them with the flow-through from step (2).
Note: Once the column reservoir is empty, immediately add the same volume of buffer for the washing steps.
(4) Remove the column and place it on a new collection tube.
(5) Elution: Add 1 mL of separation buffer to the column and use the supplied plunger to quickly elute the magnetically labeled cells.
Note: (Optional) To improve the purity of magnetically labeled cells, the eluted cells can be passed through a second MS column for re-sorting.
Precautions
The MS columns and matching plunger are supplied individually in sterile packaging. They are intended for single use and reuse is not recommended.
Prepare the separation buffer before the experiment: PBS (pH 7.2), 0.5% BSA, and 2 mM EDTA. Mix thoroughly and store at 4 °C.
Due to differences in samples and research objectives, optimal experimental conditions should be determined by the user.
