GES-1(人胃粘膜細胞)
1.Origin and General Characteristics
Cell Name | GES-1 |
Organism | Homo sapiens, human |
Age |
|
Tissue |
|
Morphology | epithelial |
Growth Properties | adherent |
Descriptions |
|
Biosafety Level |
|
2.Culture Conditions and Handling | |
Complete Growth Medium | RPMI-1640 (150110)+10% FBS (164210-500)+1% P/S (180120) |
| Remove and discard culture medium. Briefly rinse the cell layer with DPBS |
| solution to remove all traces of serum that contains trypsin inhibitor. |
| Add 1.0 to 2.0 mL of Trypsin-EDTA solution to flask and observe cells |
| under an inverted microscope until cell layer is dispersed (usually within 3 |
Subculturing | to 5 minutes). Cells that are difficult to detach may be placed at 37°C to |
| facilitate dispersal. |
| Add 4.0 to 6.0 mL of complete growth medium and aspirate cells by gently |
| pipetting. Add appropriate aliquots of the cell suspension to new culture |
| vessels. |
Subc*tion Ratio | 1:2-1:4 |
Medium Renewal | every 2 to 3 days |
Cryopreservation | Freeze medium: 50% basal medium+40% FBS+10% DMSO |
Storage temperature: liquid nitrogen vapor phase | |
| |
Culture Conditions | Atmosphere: Air, 95%; CO2, 5% |
Temperature: 37℃ | |

收到常溫細胞后如何處理?
(細胞培養詳細操作步驟請參照郵件附件)
- 首先,觀察細胞培養瓶是否完好,培養液是否有漏液、渾濁等現象。若有,請拍照,并及時與(所拍照片將作為后續服務依據)。
- 用 75%酒精擦拭細胞培養瓶表面,顯微鏡下觀察細胞狀態。因運輸問題,部分貼壁細胞會有少量從瓶壁脫落;先不要打開培養瓶蓋,將細胞置于細胞培養箱內靜置培養 2-4 小時,以便穩定細胞狀態。
- 仔細閱讀細胞說明書,了解細胞相關信息,如貼壁特性(貼壁/懸浮)、細胞形態、所用基礎培養基、血清比例、所需細胞因子、傳代比例、換液頻率等。
- 靜置完成后,取出細胞培養瓶,鏡檢、拍照,記錄細胞狀態(所拍照片將作為后續服務依據);建議細胞傳代培養后,定期拍照、記錄細胞生長狀態。
- 貼壁細胞:若細胞生長密度超過 80%,可正常傳代;若未超過 80%,移除細胞培養瓶內培養基,預留 5ml 左右繼續培養,直至細胞密度達 80%左右再進行傳代操作,瓶蓋可稍微擰松。
- 懸浮細胞:將細胞培養瓶內液體全部轉移至 50ml 無菌離心管內,1200rpm 離心 5min,離心后上清培養基可收集備用,管底細胞沉淀加入 5ml 培養基吹打、重懸。鏡檢時,若細胞密度超過 80%,可將細胞懸液分至 2 個細胞培養瓶內培養,補加培養基至 5ml;若細胞密度未超過 80%,將細胞懸液移至原瓶繼續培養,直至細胞密度達 80%左右時再進行傳代操作。
