Purpose and BackgroundsCHO lec 3.2.8.1 cellsCHO Lec 3.2.8.1 cells have four independent mutations in the N- and O- glycosylation pathways (Stanley, 1989). N-linked carbohydrates produced by CHO Lec 3.2.8.1 cells are all of the high mannose type, but differ in the number of mannoses, ranging from Man9 to Man5. O-glycosylation is homogenous, with only a single GalNAc residue attached per site. When cultured in the......阅读全文

CO2恒温摇床解决人胚肾－293－(HEK293)－细胞结团问题（一）
人胚肾 293 (HEK293) 细胞在重组蛋白表达中是最常见的宿主细胞。 这类细胞能够表达大量的膜蛋白，如 G 蛋白偶联受体 (GPCR) ，是无法在最常见的生物制药生产宿主，如：中国仓鼠卵巢 (CHO) 细胞中作表达。 HEK293 虽然是蛋白表达的极好宿主，然而 HEK293 细胞
关于红斑狼疮细胞(LEC)的简介
系统性红斑狼疮患者血液内的红斑狼疮因子，是一种抗核蛋白的免疫球蛋白G(IgG)抗体，它作用于细胞膜，使得细胞膜受损，并使细胞核胀大形成一种均匀无结构的圆形烟雾状物质，这种物质被多形核白细胞吞噬后，形成红斑狼疮细胞。检测血液中有无中性多形核白细胞吞噬均匀体的现象，即可对系统性红斑狼疮进行诊断。
