Poster Scale-up and process economy calculations of a dAb purification process using ready-to-use products
A three-step dAb purification process was used as model. The results show that although operating expenses can be more extensive when scale and number of batches increase, ready-to-use equipment and r…

Article E. coli growth and Dab expression in single-use and stainless steel fermentors
Cell growth, cell density, and Dab expression levels were assessed and compared between the two production vessels. The  results show that the performance of the XDR-50 MO fermentor is comparable …

Article A Platform Approach for the Purification of Domain Antibodies (Dabs)
This platform approach, based on a capture step with Capto L, enables increased efficiency and productivity in developing therapeutics based on Dabs. Click here to download the application not…

Article Exploring the world of antibodies: mAbs, Fabs, dAbs, and bsAbs
There is a vast array of antibody variants, including multispecific (msAb), bispecific antibodies (bsAb), antibody fragments (Fab, dAb, scFv), and antibody-drug conjugates (ADC). But with this…

Article Testa Challenge 2020 Attracts Leading International Bioprocessing Innovators
The 2020 challenge required entrants to show how their product or service would improve a real-life start to finish bioprocess run in the Testa facility by producing and purifying a dAb domain antibod…

Article High-Throughput Process Development in an Historical Environment
The challenge was to use HTPD workflows for maximized Dab purity and yield. A workshop held by Ashley Hesslein from Bayer HealthCare kicked off the meeting. The topic was “Lessons Learned in Build…

Article Protein L affinity resin is ready to move to manufacturing
After comparing resin performance for mAb, Fab, and dAb samples, MabSelect™ VL protein L resin offered increased binding capacities versus other resins. This improvement could address existing protein…
