產品特色

・無需使用飼養細胞，即可從人外周血單核細胞（PBMC）擴增自然殺傷（NK）細胞。

・在2至3週的培養中，NK細胞可以擴增數百至數千倍。

・一個試劑盒足以使用20-50 mL全血擴增NK細胞患者。

・僅供研究使用。

  • Natural killer (NK) cells can be expanded from human peripheral blood mononuclear cells(PBMCs) without using feeder cells.
  • NK cells can be expanded several hundred to several thousand-fold in 2 to 3 weeks of culture.
  • One kit is sufficient to expand NK cells patients using 20-50 mL each of the whole blood.
  • Research use only.

Procedures

・Preparing reagents

  • NK Cell Initial Medium and NK Cell Subculture Medium should be supplemented with 5 % (v/v) of heat-inactivated FBS or autologous plasma.

  • ・Preparing peripheral blood mononuclear cells (PBMCs)

  • PBMCs should be isolated from the whole blood by density gradient centrifugation using Ficoll-Paque.

  • ・Washing an NK cell Initial Flask

  • 10 ml PBS should be added to an NK Cell Initial Flask. Slant the flask to cover the entire surface with PBS. Aspirate the liquid completely from the flask. Care should be taken not to scratch the inner surface of the flask. Repeat the washing process two more times.

  • ・Culturing NK cells from PBMCs

  • PBMCs should be suspended in the NK Cell Initial Medium at 1 x 106 cells/ml. Add 40 μl of NK Cell Initial Cocktail to the 1 ml of the cell suspension. Seed the cells onto the pre-washed NK Cell Initial Flask, and incubate under 5 % CO2 at 37 ℃ for 3 days.

  • ・Changing medium and sub-culturing

  • Transfer floating as well as adherent cells to conical centrifuge tube and centrifuge at 200 x g for 8 minutes. Remove the supernatant and re-suspended the cells at 1 x 106 cells/ml in the NK Cell Subculture Medium supplemented with 5 % (v/v) of heat- inactivated FBS or autologous plasma. The cell suspension is transferred to conventional culture flasks and incubated under 5 % CO2 at 37 ℃. Cells should be sub-cultured every 2 - 3 days by suspending cells in the completed NK Cell Subculture Medium at 0.8 x 106 cells/ml.

  • ・Suggested culturing period: 2 to 3 weeks.

Other supplies required

Ficoll-Paque (GE Healthcare, Sweden)

  • Sterile PBS
  • FBS or autologous plasma (It is desirable to have them heat-inactivated at 56 ℃ for 30 minutes.)
  • Sterile conical centrifuge tubes
  • Sterile culture flasks

Precautions

NK Cell Initial Flask may carry condensation on the surface, which does not adversely affect the performance of the kit.

  • This product contains human plasma albumin.

  • 培養袋連接管
材料安全資料表
應用資料
準備流程
  • 準備試劑 NK細胞初始培養基及NK細胞傳代培養基中應添加5%（v/v）的熱滅活FBS或自體血漿。
  • 週邊血單一核細胞（PBMC）的製備
  • 應使用 Ficoll-Paque 透過密度梯度離心從全血中分離 PBMC。
  • ・清洗 NK 細胞初始培養瓶
  • 應將 10 ml PBS 加入 NK 細胞初始燒瓶中。傾斜燒瓶，用 PBS 覆蓋整個表面。將燒瓶中的液體完全吸出。應注意不要刮傷燒瓶的內表面。再重複洗滌過程兩次。
  • ・從 PBMC 培養 NK 細胞
  • PBMC 應以 1 x 106 個細胞/ml 的濃度懸浮在 NK 細胞初始培養基中。將 40 μl NK 細胞初始混合物加入 1 ml 細胞懸浮液中。將細胞接種到預洗的 NK 細胞初始培養瓶中，並在 5% CO2、37℃ 下培養 3 天。
  • ・更換培養基及傳代培養
  • 將漂浮細胞和貼壁細胞轉移至錐形離心管中，並以 200 xg 離心 8 分鐘。除去上清液，並將細胞以 1 x 106 個細胞/ml 重新懸浮在補充 5% (v/v) 熱滅活 FBS 或自體血漿的 NK 細胞傳代培養基中。將細胞懸浮液轉移至常規培養瓶中，在5%CO2、37℃下培養。細胞應每 2 - 3 天進行一次傳代培養，將細胞以 0.8 x 106 個細胞/ml 懸浮在完整的 NK 細胞傳代培養基中。
  • ・建議培養時間：2至3週。
其他所需用品
  • Ficoll-Paque（GE Healthcare，瑞典）
  • 無菌PBS
  • FBS或自體血漿（最好56℃熱滅活30分鐘）
  • 無菌錐形離心管
  • 無菌培養瓶
預防措施
  • NK 細胞初始瓶的表面可能會出現凝結，這不會對試劑盒的性能產生不利影響。
    本品含有人類血漿白蛋白。
