| Permits/Forms: | In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimately responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location. | ||
| Applications: | transfection host (Roche Transfection Reagents ) | ||
| Tumorigenic: | Yes | ||
| DNA Profile (STR): | Amelogenin: X CSF1PO: 10 D13S317: 10,11 D16S539: 8,13 D5S818: 12,13 D7S820: 8,12 THO1: 10 TPOX: 8 vWA: 18,19 |

| Cytogenetic Analysis: | This is a hypotriploid human cell line. The modal chromosome number is 58 occurring at 30%. The frequency of higher ploidies was 3.2%. Over 30 marker chromosomes were common to all cells, and four others were found in some cells. Among the common markers were 1q+, t(1q8q), 2q+, der(16)t(3;16)(q21;q22), der(19)t(13;19)(q21;q13), and der(5)t(5;5)(p15pq13). Generally, there were two copies of der(5) in each cell. Normal Y and D group chromosomes were absent, and the X chromosome was single. | ||
| Isoenzymes: | AK-1, 1 ES-D, 1 G6PD, B GLO-I, 2 Me-2, 0 PGM1, 1 PGM3, 1 |
||
| Gender: | male | ||
| Comments: | The NCI-H520 cell line was derived by A.F. Gazdar and associates in 1982 from a sample of a lung mass taken from a patient with squamous cell carcimoma of the lung. The cells express greatly reduced levels of p53 mRNA relative to normal lung tissue, but exhibit no gross structural DNA abnormalities. The cells stain positively for keratin and vimentin but are negative for neurofilament triplet protein. The line can be cloned in soft agar (with or without serum). |
||
| Propagation: | ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. Temperature: 37.0°C |
||
| Subculturing: | Protocol: Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks. Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended Medium Renewal: 2 to 3 times per week |
||
| Preservation: | Freeze medium: Complete growth medium, 95%; DMSO, 5% Storage temperature: liquid nitrogen vapor temperature |
||
| Doubling Time: | 61 hrs in medium with serum; 25 to 32 hrs in serum-free medium | ||
| Related Products: | Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001 recommended serum:ATCC 30-2020 |

文献和实验NCI-H526来源于一名55岁白人男性小细胞肺癌（Stage E）患者的骨转移灶，从肺部分离获得。该细胞高表达两个小细胞肺癌生化标志物——神经元特异性烯醇化酶和脑肌酸激酶同工酶，是肺癌研究中常用的体外模型之一。 形态特征与生长方式 悬浮生长，细胞以大量聚团形式存在。刚复苏时细胞是分散的，24-48小时后状态逐渐恢复，开始聚团生长。传代时不需要完全吹散成单细胞，把大团吹成小团即可，避免团块中间的细胞缺乏营养。 培养要点与注意事项 培养基选用1640添加10%胎牛血清及1%双抗
都是贴壁细胞，在消化传代过程中，步骤如下：倒尽旧的培养液－＞用无血清的培养基清洗一两次－＞加入一定量的胰酶，置于37度培养箱中5--10分钟，使细胞悬浮－＞显微镜下观察，待细胞大部分变圆时，回到超静台－＞加入一定量的含血清的新培养液，以终止胰酶作用－＞反复吹打细胞－＞再置显微镜下观察，直到细胞全部悬浮起来－＞吸出一部分加入新的培养瓶中－＞最后再补充加入一定量新的培养液。注意： 1、吹细胞时尽量多吹边角儿，此处细胞生长的多。2、吸出细胞前要混匀，可以剧烈震荡培养瓶。3、我们用的是DMEM
