   sw480細(xì)胞源自一位51歲白人男性的原位直腸腺癌，而SW620源自同一病人一年后的淋巴結(jié)轉(zhuǎn)移灶。該細(xì)胞CSAp和直腸抗原3陰性；角蛋白陽性；p53基因第273位密碼子的G→A突變引起Arg→His替代，309位密碼子的C→T突變導(dǎo)致Pro→Ser替代；細(xì)胞p53蛋白表達(dá)水平升高；癌基因c-myc、K-ras、H-ras、N-ras、myb、sis和fos的表達(dá)呈陽性；未檢測到癌基因N-myc的表達(dá)；不表達(dá)Matrilysin（一種與腫瘤侵襲相關(guān)的金屬蛋白酶）。有報(bào)道稱該細(xì)胞表達(dá)GM-CSF。

  sw480細(xì)胞 L-15空氣培養(yǎng)注意要點(diǎn)：

1. 空氣培養(yǎng)注意要點(diǎn)： 

a) 人結(jié)腸腺癌細(xì)胞（SW480）使用L15空氣培養(yǎng)基。 L-15 采用磷酸鹽和游離氨基酸而非進(jìn)行緩沖。這種培養(yǎng)基適用 于支持非 CO2 平衡環(huán)境中的細(xì)胞生長。在使用該培養(yǎng)體系時(shí)，須將培養(yǎng) 箱的二氧化碳濃度調(diào)節(jié)至“0”（維持空氣培養(yǎng)狀態(tài)），如果通入5%二氧化 碳通過培養(yǎng)基對細(xì)胞產(chǎn)生毒性。

 b) 如您沒有無空氣培養(yǎng)箱，可選擇使用不透氣培養(yǎng)瓶（密封瓶蓋）培養(yǎng)該 細(xì)胞，并將瓶蓋擰緊，每次操作時(shí)開蓋短時(shí)間接觸到的二氧化碳不影響該細(xì)胞正常培養(yǎng)。

         圖示：密封瓶蓋培養(yǎng)瓶（左）和透氣瓶蓋培養(yǎng)瓶（右）

 注意：可以選用 SW480細(xì)胞專用培養(yǎng)基（即用型培養(yǎng)基）： 已添加血清和雙抗等成分，可直接用于培養(yǎng)SW480細(xì)胞。
