Concentrating Feed—an Applicable Approach to Improve Antibody Production
Because the feed dilutes the culture and reduces product concentration, the use of lower feed volumes can improve overall process productivity as well.
One approach of decreasing feed vol…

Automated Concentration and Diafiltration of Multiple siRNA Samples
Once the duplex is confirmed to have minimal excess of either single strand, the siRNA product requires diafiltration and concentration using ultrafiltration methods. These methods remove residual sal…
