Recent developments have made small-scale antibody expression much easier. Upstream scientists can express tens or hundreds of antibodies in parallel. Analysis of purified samples at early stage will likely improve long-term success rate because there will be a reduction in interference of impurities.

In antibody sequencing, a small quantity of antibodies with decent purity are needed for subsequent processes. Many antibody sequencing companies also need to provide clients at least milligrams of purified antibody along with sequencing reports.…
