摘要

研究了小鼠抗f9血清对大鼠胚胎癌细胞(F3/1)的反应性,以及异种和同种宿主对F3/1细胞的免疫反应。免疫荧光法检测小鼠抗f9血清在F3/1细胞表面有反应。然而,同样的抗血清对F3/1细胞没有细胞毒性。在体内和体外实验中,F3/1细胞在同基因宿主中无免疫原性。因此,在本研究中,F3/1抗原不能用同基因抗血清确定,只能用异种抗F3/1血清的非细胞毒性表面结合抗体(IgG)确定。

Immunological properties of rat embryonal carcinoma cells

The reactivity of mouse anti-F9 serum on rat embryonal carcinoma cells (F3/1) and xenogeneic as well as syngeneic host immune responses against F3/1 cells were studied. Mouse anti-F9 serum was reactive on the cell surface of F3/1 cells by immunofluorescence. The same antiserum, however, was not cytotoxic against F3/1 cells. The F3/1 cells were not immunogenic in syngeneic hosts as tested by in vivo and in vitro assays. Thus, in the present study, F3/1 antigen(s) could not be defined with syngeneic antiserum but only defined with non-cytotoxic, surface-binding antibodies (IgG) of xenogeneic anti-F3/1 serum.
