Analytical Development


Kemwell offers analytical services for mammalian cell culture-based products to support your clinical and commercial product needs. Our efficient and strong Analytical Development team is unified into R&D services. 

Kemwell provides analytical method development and method validation services. Development approach covers all aspects for the intended use of the method (stability indicating, process development support, limits of detection/ quantitation, etc.). The extent of method validation studies are based on the stage of product development and comply with the industry guidelines.

The analytical team in support of QC establishes reference standards based on regulatory requirements thorough characterization and comparability establishment. The reference standards are then stored under cGMP conditions.
