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.
