## Scale-up and quality control

For consistent and scalable production, we offer:

- Stable expression populations (CHO, hybridoma) 
- High-expression CHO cell clone  
- Master and working cell bank (MCB/WCB)   
   

Single clone CHO MCB and WCB workflow (in case of CHO cells)

\*MCB and WCB can also be generated from the transfectant population, when appropriate.

For quality management/control of repeated productions, we offer:

- Delivery of up to three independently produced test batches for client evaluation 
- SOP & QC protocol development

#### About MBL

MBL was founded in 1969 as the first manufacturer of antibodies in Japan. Using technology built on advances in immunology and molecular biology, MBL offers clinical diagnostics and research reagents designed for analysis of proteins and/or genes associated primarily with autoimmune disorders, cancer, gynecological diseases, and infectious diseases. In recent years MBL has also been actively developing biomarker reagents and companion diagnostics, taking advantage of our strength in immunological and gene detection techniques.
