Objective: To study the expression of murine stem cell factor in CHO cells.
目的：克隆造血干细胞因子并在CHO细胞中表达。
AIM: TO obtain high level expression of recombinant human truncated osteoprotegerin (TOPG) with higher bioactivity in CHO-DHFR-cells.
实现其在CHO - DHFR -细胞中的高效表达，获取生物活性较高的重组蛋白。
CONCLUSION: MTX induced-increase of recombinant antibody production in CHO cells can be increased by weakening the expression of DHFR gene.
结论：弱化表达载体中DHFR的表达，可提高MTX对工程抗体表达的增加效果。
Conclusion: MTX selection should be timely used to overcome the instability of the expression of anti HBsAg in CHO HB2 cells.
结论：应及时用MTX对细胞株进行再加压筛选以及保存，以保持细胞稳定表达抗体的能力；
