GES-1(人胃粘膜細(xì)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(xì)胞后如何處理?
(細(xì)胞培養(yǎng)詳細(xì)操作步驟請(qǐng)參照郵件附件)
- 首先,觀察細(xì)胞培養(yǎng)瓶是否完好,培養(yǎng)液是否有漏液、渾濁等現(xiàn)象。若有,請(qǐng)拍照,并及時(shí)與(所拍照片將作為后續(xù)服務(wù)依據(jù))。
- 用 75%酒精擦拭細(xì)胞培養(yǎng)瓶表面,顯微鏡下觀察細(xì)胞狀態(tài)。因運(yùn)輸問(wèn)題,部分貼壁細(xì)胞會(huì)有少量從瓶壁脫落;先不要打開(kāi)培養(yǎng)瓶蓋,將細(xì)胞置于細(xì)胞培養(yǎng)箱內(nèi)靜置培養(yǎng) 2-4 小時(shí),以便穩(wěn)定細(xì)胞狀態(tài)。
- 仔細(xì)閱讀細(xì)胞說(shuō)明書(shū),了解細(xì)胞相關(guān)信息,如貼壁特性(貼壁/懸?。?/span>、細(xì)胞形態(tài)、所用基礎(chǔ)培養(yǎng)基、血清比例、所需細(xì)胞因子、傳代比例、換液頻率等。
- 靜置完成后,取出細(xì)胞培養(yǎng)瓶,鏡檢、拍照,記錄細(xì)胞狀態(tài)(所拍照片將作為后續(xù)服務(wù)依據(jù));建議細(xì)胞傳代培養(yǎng)后,定期拍照、記錄細(xì)胞生長(zhǎng)狀態(tài)。
- 貼壁細(xì)胞:若細(xì)胞生長(zhǎng)密度超過(guò) 80%,可正常傳代;若未超過(guò) 80%,移除細(xì)胞培養(yǎng)瓶?jī)?nèi)培養(yǎng)基,預(yù)留 5ml 左右繼續(xù)培養(yǎng),直至細(xì)胞密度達(dá) 80%左右再進(jìn)行傳代操作,瓶蓋可稍微擰松。
- 懸浮細(xì)胞:將細(xì)胞培養(yǎng)瓶?jī)?nèi)液體全部轉(zhuǎn)移至 50ml 無(wú)菌離心管內(nèi),1200rpm 離心 5min,離心后上清培養(yǎng)基可收集備用,管底細(xì)胞沉淀加入 5ml 培養(yǎng)基吹打、重懸。鏡檢時(shí),若細(xì)胞密度超過(guò) 80%,可將細(xì)胞懸液分至 2 個(gè)細(xì)胞培養(yǎng)瓶?jī)?nèi)培養(yǎng),補(bǔ)加培養(yǎng)基至 5ml;若細(xì)胞密度未超過(guò) 80%,將細(xì)胞懸液移至原瓶繼續(xù)培養(yǎng),直至細(xì)胞密度達(dá) 80%左右時(shí)再進(jìn)行傳代操作。
