簡介 | 人自然殺傷性細胞NK92是從一位患有急進性非霍奇金淋巴瘤的50歲白人男性外周血單核細胞衍生來的一株白細胞介素-2依賴型NK細胞株。NK-92MI是轉染得到的源自NK-92的IL-2非依賴的NK細胞株,親本細胞通過微粒體基因轉化法用逆轉錄病毒MFG-hIL-2載體攜帶的人IL-2cDNA進行轉化。可能由于載體整合到基因組DNA中,轉化是穩(wěn)定的。這株細胞對很多惡性細胞有細胞毒性;鉻釋放試驗顯示它能殺死K562和Daudi細胞。NK-92細胞有以下特征:CD2 +, CD7 +, CD11a +, CD28 + , CD45 +, CD54 +, CD56 +, CD1 -, CD3 -, CD4 -, CD5 -, CD8 -, CD10 -, CD14 -, CD16 -, CD19 -, CD20 -, CD23 -, CD34 -, HLA-DR -。另本庫保藏有NK92MI細胞。二者均引種自ATCC。 | ||
補充 | NK92細胞培養(yǎng)時,會有零星聚團現象,此時吹打散開即可。處于平臺期的細胞,會有少量呈現略不規(guī)則的圓形,此為正?,F象。血清建議使用BCK北美胎牛血清(貨號BCK041)與BCK馬血清(貨號BCK045)。 | ||

驗收細胞注意事項
1、收到人自然殺傷性細胞NK92細胞,請查看瓶子是否有破裂,培養(yǎng)基是否漏出,是否渾濁,如有請盡快聯系。
2、收到人自然殺傷性細胞NK92細胞,如包裝完好,請在顯微鏡下觀察細胞。,由于運輸過程中的問題,細胞培養(yǎng)瓶中的貼壁細胞有可能從瓶壁中脫落下來,顯微鏡下觀察會出現細胞懸浮的情況,出現此狀態(tài)時,請不要打開細胞培養(yǎng)瓶,應立即將培養(yǎng)瓶置于細胞培養(yǎng)箱里靜止 3-5 小時左右,讓細胞先穩(wěn)定下,再于顯微鏡下觀察,此時多數細胞會重新貼附于瓶壁。如細胞仍不能貼壁,請用臺盼藍染色法鑒定細胞活力,如臺盼藍染色證實細胞活力正常請按懸浮細胞的方法處理。
3、收到人自然殺傷性細胞NK92細胞后,請鏡下觀察細胞,用恰當方式處理細胞。若懸浮的細胞較多,請離心收集細胞,接種到一個新的培養(yǎng)瓶中。棄掉原液,使用新鮮配制的培養(yǎng)基,使用進口胎牛血清。剛接到細胞,若細胞不多時 血清濃度可以加到 15%去培養(yǎng)。若細胞迏到 80%左右 ,血清濃度還是在 10%。
4、收到人自然殺傷性細胞NK92細胞時如無異常情況 ,請在顯微鏡下觀察細胞密度,如為貼壁細胞,未超過80%匯合度時,將培養(yǎng)瓶中培養(yǎng)基吸出,留下 5-10ML 培養(yǎng)基繼續(xù)培養(yǎng):超過 80%匯合度時,請按細胞培養(yǎng)條件傳代培養(yǎng)。如為懸浮細胞,吸出培養(yǎng)液,1000 轉/分鐘離心 3 分鐘,吸出上清,管底細胞用新鮮培養(yǎng)基懸浮細胞后移回培養(yǎng)瓶。
5、將培養(yǎng)瓶置于 37℃培養(yǎng)箱中培養(yǎng),蓋子微微擰松。吸出的培養(yǎng)基可以保存在滅菌過的瓶子里,存放于 4℃冰箱,以備不時之需。
6、24 小時后,人自然殺傷性細胞NK92細胞形態(tài)已恢復并貼滿瓶壁,即可傳代。(貼壁細胞)將培養(yǎng)瓶里的培養(yǎng)基倒去,加 3-5ml(以能覆蓋細胞生長面為準)PBS 或 Hanks’液洗滌后棄去。加 0.5-1ml 0.25%含 EDTA 的胰酶消化,消化時間以具體細胞為準,一般 1-3 分鐘,不超過 5 分鐘。可以放入37℃培養(yǎng)箱消化。輕輕晃動瓶壁,見細胞脫落下來,加入 3-5ml 培養(yǎng)基終止消化。用移液管輕輕吹打瓶壁上的細胞,使之*脫落,然后將溶液吸入離心管內離心,1000rpm/5min。棄上清,視細胞數量決定分瓶數,一般一傳二,如細胞量多可一傳三,有些細胞不易傳得過稀,有些生長較快的細胞則可以多傳幾瓶,以具體細胞和經驗為準。(懸浮細胞)用移液管輕輕吹打瓶壁,直接將溶液吸入離心管離心即可。
7、貼壁細胞 ,懸浮細胞。嚴格無菌操作。換液時,換新的細胞培養(yǎng)瓶和換新鮮的培養(yǎng)液,37℃,5%CO2 培養(yǎng)。
特別提醒: 原瓶中培養(yǎng)基不宜繼續(xù)使用,請更換新鮮培養(yǎng)基培養(yǎng)。
