Serum-free full suspension cell line ST-S strain as well as establishment and application thereof

The invention relates to the technical field of biology, and particularly provides a serum-free full suspension cell line ST-S strain as well as establishment and application thereof. The preservation number of the cell line ST-S strain is CCTCC NO: C2022226, the cell density in unit volume of the cell line ST-S strain is high, the maintenance time of the cell viability is long, and the process amplification of a production scale can be completely met. Meanwhile, the strain is sensitive to various viruses and can be used for suspension culture of a series of viruses. 本发明涉及生物技术领域，具体提供一种无血清全悬浮细胞系ST-S株及其建立与应用。该细胞系ST-S株保藏编号为CCTCCNO：C2022226，其单位体积内细胞密度高，细胞活率的维持时间长，完全能够满足生产规模的工艺放大。同时对多种病毒均敏感，可用于一系列病毒的悬浮培养。
