Abstract

We have obtained a hybridoma clone, JLJ5a, which secretes monospecific antibody directed against a 110-kdalton protein of gerbil fibroma cells, Rat-1 fibroblasts, and L6 myoblasts. It appears to be localized in the Golgi apparatus by the following criteria: (a) In double-staining experiments the localization of the 110-kdalton protein by the JLJ5a monoclonal antibody was coincident with the reaction products of thiamine pyrophosphatase (one of the enzyme markers of the Golgi apparatus; Novikoff and Goldfischer, 1961, Proc. Natl. Acad. Sci. U.S.A. 47:802-810) in the same cells. (b) The staining pattern of the JLJ5a monoclonal antibody became fragmented and dispersed into vacuoles after pretreatment of the cells with Colcemid or monensin.

摘要

我们获得了一个杂交瘤克隆JLJ5a,它分泌针对沙鼠纤维瘤细胞、大鼠-1成纤维细胞和L6成肌细胞中一种110 kDa蛋白质的单特异性抗体。根据以下标准,它似乎定位于高尔基体:(a) 在双重染色实验中,JLJ5a单克隆抗体对110 kDa蛋白质的定位与同一细胞中硫胺焦磷酸酶(高尔基体的酶标志物之一;诺维科夫和戈德菲舍尔,1961年,美国国家科学院院刊47:802 - 810)的反应产物一致。(b) 在用秋水仙酰胺或莫能菌素预处理细胞后,JLJ5a单克隆抗体的染色模式变得碎片化并分散到液泡中。
