| 細(xì)胞描述 |
NK-92 and this derivative cell line NK-92MI have the following characteristics: surface marker positive for CD2, CD7, CD11a, CD28, CD45, CD54 and CD56 bright; surface marker negative for CD1, CD3, CD4, CD5, CD8, CD10, CD14, CD16, CD19, CD20, CD23, CD34 and HLA-DR. The parental IL-2 dependent cell line is available as NK-92. NK- 92MI was shown to contain, express, and synthesize the hIL-2. A culture submitted to the ATCC in September of 1998 was found to be contaminated with mycoplasma. Progeny were cured by a 21-day treatment with BM Cycline. The cells were assayed for mycoplasma, by the Hoechst stain, PCR and the standard culture test, after a six-week period following treatment. All tests were negative. ATCC confirmed this cell line is positive for the presence of Epstein-Barr viral DNA sequences via PCR. |
| 細(xì)胞傳代步驟 |
如果細(xì)胞密度達(dá)80%-90%，即可進(jìn)行傳代培養(yǎng)。1. 棄去培養(yǎng)上清，用不含鈣、鎂離子的PBS潤洗細(xì)胞1-2次。2. 加2ml消化液（0.25%Trypsin-0.53mM EDTA）于培養(yǎng)瓶中，置于37℃培養(yǎng)箱中消化1-2分鐘，然后在顯微鏡下觀察細(xì)胞消化情況，若細(xì)胞大部分變圓并脫落，迅速拿回操作臺，輕敲幾下培養(yǎng)瓶后加少量培養(yǎng)基終止消化。3. 按6-8ml/瓶補加培養(yǎng)基，輕輕打勻后吸出，在1000RPM條件下離心4分鐘，棄去上清液，補加1-2mL培養(yǎng)液后吹勻。4. 將細(xì)胞懸液按1：2到1：5的比例分到新的含8ml培養(yǎng)基的新皿中或者瓶中 |
| 復(fù)蘇細(xì)胞步驟 |
將含有1mL細(xì)胞懸液的凍存管在37℃水浴中迅速搖晃解凍，加入4mL培養(yǎng)基混合均勻。在1000RPM條件下離心4分鐘，棄去上清液，補加1-2mL培養(yǎng)基后吹勻。然后將所有細(xì)胞懸液加入培養(yǎng)瓶中培養(yǎng)過夜（或?qū)⒓?xì)胞懸液加入10cm皿中，加入約8ml培養(yǎng)基，培養(yǎng)過夜）。第二天換液并檢查細(xì)胞密度。 |
| 細(xì)胞凍存步驟 |
：待細(xì)胞生長狀態(tài)良好時，可進(jìn)行細(xì)胞凍存。下面T25瓶為例；1．細(xì)胞凍存時，棄去培養(yǎng)基后，PBS清洗瓶底1-2次后加入1ml胰酶，細(xì)胞變圓脫落后，加入2ml完全培養(yǎng)基終止消化，可使用血球計數(shù)板計數(shù)。2．1000RPM離心5分鐘去掉上清。用血清重懸浮，加DMSO至最終濃度為10%。加入DMSO后迅速混勻，按每1ml的數(shù)量分配到凍存管中，注意凍存管做好標(biāo)識。本公司按每個凍存管細(xì)胞數(shù)目大于1X106個細(xì)胞凍存。3．將凍存管置于程序降溫盒中，放入-80度冰箱，至少2個小時以后轉(zhuǎn)入液氮灌儲存。記錄凍存管位置以便下次拿取。 |
