  • 服务介绍
  • 公司简介

 

Development of a stable cell line based on CHO or NS0 for production of recombinant proteins and monoclonal antibodies is unavoidable for some applications such as clinical use, when mammalian cell expression system is pursued. However, stable cell line generation is mostly thought as time and cost-consuming work.

ACRObiosystems' provide commercial and research CHO(DG44, DUKX-B11, CHO-S or CHO-K1) cell line based on its proprietary expression vector, high throughput cell screening technologies and serum,animal components free process without any adaptation issue in a significantly reduced timeline
