| 細(xì)胞描述 |
This cell line is one of four colorectal adenocarcinoma cell lines that have been identified as being derived from a single individual. DNA profiling studies [1,2] have shown that DLD-1, HCT-15, HCT-8 and HRT-18G share a single profile. DNA fingerprinting and cytogenetic analyses performed at ATCC and elsewhere show the line is similar to HCT-15 and suggest the two are of different clonal origin from the same individual. Their genetic origin has been confirmed by DNA fingerprinting; however, cytogenetic analysis has shown that they lack concurrent marker chromosomes or concurrent numerical changes. A culture of unknown passage submitted to the ATCC in 1979 was found to be contaminated with Mycoplasma hyorhinis. The cells were subsequently cured using a combination of antibiotics over a 12-week cultivation period. Following treatment, the cells were assayed by the Hoechst stain weekly and by the standard culture test periodically. During 11 consecutive months of cultivation in the absence of |
| 細(xì)胞傳代步驟 |
如果細(xì)胞密度達(dá)80%-90%，即可進行傳代培養(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。 |
