WebTwo clones each carrying eleven gene copies, expressing HSA under control of PG1 and PG6 respectively were generated by post-transformational vector amplification. They produced about 1.0 and 0.7 g L-1 HSA respectively in equal fed batch processes. The suitability in production processes was also verified with HyHEL antibody Fab fragment for ... WebPost-transformational vector amplification was used to generate clones containing up to five copies of HSA. However it was not possible to correlate copy number and yield as 15 L bioreactor cultures showed significant genetic instability. The mean final copy number was 2.6 ± 1.0. Further work was undertaken to evaluate possible ways to prevent ...
