Raman’s role in large molecule development 

Large molecule development and therapeutics is a segment of the life science industry that usually targets specific population groups to treat specific diseases. The process involves optimizing the protein production machinery of the cells in a living host.  

We understand some challenges to manufacturing in the biopharmaceutical industry are:

  1. Researchers must iteratively optimize the host cell genetics, culture conditions, and identify the best potential therapeutic molecule from a pool of thousands. 
  1. Scientists must reprove analytical methods and equipment for the process/production environment during subsequent stages of development.  
  1. Lack of real-time insights into the process also hinders quality control. Off-line manual sampling is inconsistent and slow to produce results, leading to inconsistent product quality.  

Raman spectroscopy overcomes these challenges by offering continuous monitoring of multiple attributes with a single in situ probe. Also, a single analyzer paired with multiple probes enables in-line, real-time bioprocess monitoring and control of several process streams, including asynchronous unit operations. Manufacturers can use Raman to improve product quality, speed up cycle times, increase yields, and perform cross-scale method transfer from lab to manufacturing. 

In addition, Raman spectroscopy aligns with industry initiatives like Process Analytical Technology (PAT) and Quality by Design (QbD). The technology enables in-line control and optimization of the process as well as better quality assurance and risk management. 

Recent Raman advances in bioprocessing 

The use of Raman technology in the biopharma industry has been growing over the last few decades. One of the most significant innovations in Raman technology for bioprocessing is lab-to-process scalability. Raman systems are now commercially available with analyzers, probes, software, and accessories compatible with all stages of bioprocessing. This scalability offers significant advantages during product development. 

New Raman probes meet the exacting biopharma industry requirements, including strict material standards, sterilization, port compatibility, and convenience. They feature stainless steel surfaces, fit the ports of small and large-scale bioreactors, and offer compatibility with cleaning and sterilization protocols.  

Raman technology partnerships are also creating new opportunities for high throughput process development to generate robust models from a single run. The resulting Raman instruments integrate with micro and mini bioreactor systems and single-use production bioreactors. 

Raman technology helps achieve PAT objectives like minimizing process variability and development time while maximizing productivity, process robustness, and product quality.
