产品概述
产品信息
| 名称 | LS 174T [LS174T] (人结肠腺癌细胞) (STR鉴定正确) |
| 别称 | Ls174T; LS174t; Ls-174-T; LS-174-T; LS 174 T; LS-174T; Ls-174T; LS 174T; LS-174; LS174 |
| 背景描述 | LS 174T细胞是LS 180细胞的胰蛋白酶化变种。LS 174T细胞比亲本更易传代，像LS 180细胞一样生成大量的癌胚抗原(CEA)。电镜研究表明，LS 174T细胞有丰富的微丝和细胞质粘液素液泡。LS 174T细胞直肠抗原3阳性；p53抗原表达阴性，但mRNA表达阳性。LS 174T细胞角蛋白染色阳性；LS 174T细胞癌基因c-myc、N-myc、H-ras、N-ras、Myb和fos的表达呈阳性；癌基因k-ras和sis的表达未做检测。 |
