| Comments: | The Daudi line was derived from a 16-year-old Black male with Burkitt's lymphoma by E. Klein and G. Klein in May, 1967. The cells are negative for beta-2-microglobulin. They are positive for EBNA, VCA and Surface immunoglobulin (sIg+). The line carries Epstein-Barr virus. The Daudi is a well characterized B lymphoblast cell line which has been employed extensively in studies of mechanisms of leukemogenesis. | ||
| 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%. Atmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 37.0°C |
||
| Subculturing: | Protocol: Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 3 to 5 X 10(5) viable cells/ml. Interval: Maintain cell density between 3 X 10(5) and 2 to 3 X 10(6) viable cells/ml. Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density) |
||
| Preservation: | Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO Storage temperature: liquid nitrogen vapor phase |
||
| Related Products: | Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001 recommended serum:ATCC 30-2020 |

【摘要】目的 构建抗CD20嵌合抗体Fab'和F(ab)2片段表达载体,并在大肠杆菌中进行高效可溶性分泌表达,比较二者的活性差异。方法 从相应的杂交瘤中提取mRNA建立抗CD20 ScFv 噬菌体显示文库,利用PCR方法从阳性克隆扩增抗CD20抗体轻链可变区基因(VL)、重链可变区基因(VH),重组到表达载体pYZF1,构建抗CD20 Fab’和抗CD20 F(ab)2达载体pYZF1cd20和pYZcpp3,并在16c9菌中高效表达。MTT法测定Fab’和F(ab)2对Raji和Daudi
LAK细胞和TIL活性的测定基本同NK活性测定方法。但所用靶细胞为对NK不敏感的肿瘤细胞,如Raji、Daudi或自体肿瘤细胞。常采用同位素法如51 Cr释放试验、发光免疫测定法及MTT比色法等。 在此介绍MTT比色法。 试剂及材料 1. 试剂:①四甲基偶氮盐(MTT);②酸化异丙醇:含0.04mol/L HCl的异丙醇;③96孔细胞培养板。 2. 肿瘤细胞系: Raji细胞、Daudi细胞为B细胞性白血病细胞株;Molt-4为T细胞性白血病细胞,对LAK细胞敏感
