细胞描述: |
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. |
细胞传代步骤: |
如果细胞密度达80%-90%,即可进行传代培养。1. 弃去培养上清,用不含钙、镁离子的PBS润洗细胞1-2次。2. 加2ml消化液(0.25%Trypsin-0.53mM EDTA)于培养瓶中,置于37℃培养箱中消化1-2分钟,然后在显微镜下观察细胞消化情况,若细胞大部分变圆并脱落,迅速拿回操作台,轻敲几下培养瓶后加少量培养基终止消化。3. 按6-8ml/瓶补加培养基,轻轻打匀后吸出,在1000RPM条件下离心4分钟,弃去上清液,补加1-2mL培养液后吹匀。4. 将细胞悬液按1:2到1:5的比例分到新的含8ml培养基的新皿中或者瓶中 |
复苏细胞步骤: |
将含有1mL细胞悬液的冻存管在37℃水浴中迅速摇晃解冻,加入4mL培养基混合均匀。在1000RPM条件下离心4分钟,弃去上清液,补加1-2mL培养基后吹匀。然后将所有细胞悬液加入培养瓶中培养过夜(或将细胞悬液加入10cm皿中,加入约8ml培养基,培养过夜)。第二天换液并检查细胞密度。 |
细胞冻存步骤: |
:待细胞生长状态良好时,可进行细胞冻存。下面T25瓶为例;1.细胞冻存时,弃去培养基后,PBS清洗瓶底1-2次后加入1ml胰酶,细胞变圆脱落后,加入2ml完全培养基终止消化,可使用血球计数板计数。2.1000RPM离心5分钟去掉上清。用血清重悬浮,加DMSO至最终浓度为10%。加入DMSO后迅速混匀,按每1ml的数量分配到冻存管中,注意冻存管做好标识。本公司按每个冻存管细胞数目大于1X106个细胞冻存。3.将冻存管置于程序降温盒中,放入-80度冰箱,至少2个小时以后转入液氮灌储存。记录冻存管位置以便下次拿取。 |
