5 | coTIMP-2-6XHis | HEK-293-F | stable | suspension/shaker | 15 | 1.1 |
6 | coTIMP-2-6XHis | HEK-293-F | stable | suspension/shaker | 20.8 | 1.2 |
7 | coTIMP-2-6XHis | HEK-293-F | stable | suspension/spinner | 40 | 1.6 |

Production yields are significantly higher in stably transfected HEK-293-F cells vs transient transfections and using codon-optimized TIMP-2. Yields are reported for all combinations of cDNA, cell lines, and culture conditions (n = 3).
