however, neither hi nor nt antibody was detected out in the culture supernate of cells infected with the 3 strains of virus and regardless of inactivators (β-propiolactone or formalin) used.
但三株病毒感染的细胞培养上清液,用两种灭活剂均未产生hi或nt抗体。
the results showed that both the cell-free extract and culture supernate from mouse srs-82 cell line were leukemogenic.
上述研究结果表明。srs-82株的无细胞提取液和其培养上清液的离心沉淀物皆具有致白血病活性。
though there was no difference in detection rate with the three antigens, the cell culture supernate antigen was superior to other two antigens in titre and line sharpness.
三种抗原在检出率上虽无差异,但细胞上清液制备的抗原在效价、沉淀线的清晰度方面优于其它两种抗原。
