NS0

NS0是一種源自非分泌型小鼠骨髓瘤（nonsecreting murine myeloma）的細胞系，目前應用於生物醫學研究和治療型蛋白質的商業生產^[1]。NS0是一種膽固醇依賴性的細胞系，由NSI/1的一個亞系產生，而該亞系僅產生輕鏈（英语：Immunoglobulin light chain）而不會產生重鏈（英语：Immunoglobulin heavy chain）^[2]^[3]。

歷史[编辑]

在BALB/c小鼠體內分離出會分泌IgG1的MOPC21腫瘤後，從該腫瘤中分離出P3K細胞，並且發展成289-16細胞和P3-X63細胞。289-16細胞僅分泌輕鏈而不會分泌重鏈，並且被重命名為NSI/1。從該細胞系中分離出克隆，並鑑定出其為新的非分泌型細胞系，命名其為NS0/1^[2]^[4]。

用途[编辑]

作為骨髓瘤細胞的NS0細胞是具有天然抗體的懸浮細胞，並且擁有淋巴母細胞（英语：Lymphoblast）形態。基因擴增（英语：Gene amplification）通常使用經GS轉染的NS0細胞進行選擇，以產生細胞系^[5]。GS-NS0是一種異源哺乳動物表達（英语：Heterologous expression）系統，可以表達重組蛋白。使用NS0細胞可以產生達利珠單抗（英语：Daclizumab）和依庫珠單抗（英语：Eculizumab）等具治療作用的抗體產品^[6]。
