For the cell culture assay do you use any cells other than CHO, have you tried in any other cell lines?

Answer

During the early development phase we tested the product quality with various cell lines, mainly CHO cells (e.g. CHOZN, CHO-K1, CHO-S) and a few others in our R&D labs. During the later development and implementation phase of a cell culture assay we decided to use a CHO cell line for regular product release in our QC lab as this is commonly used by our customers in the biopharmaceutical industry.
