Media Optimization

Cell Culture Media
 

Our R&D capabilities are built to meet your custom medium development needs. Offering an integrated approach to medium selection, development, testing and validation, we'll deliver increased productivity. That means faster results - and a greater competitive advantage for you.

Our Development Process
Our process consists of four phases, combining multiple design approaches that work to increase performance, decrease time requirements and maximize overall medium performance against design goals.



Design Approaches

Analytical Approach - Our R&D staff select base media with the best performance characteristics (growth, productivity, etc.), speeding the selection process with a full range of analytical tools to perform raw material characterization and spent medium analysis.
Analytical Assay Lab Capabilities
Molecular Approach - Microarray analysis helps to us identify media components that might not be considered otherwise. This technique enables targeted testing for growth factors & receptors, hormones, attachment factors & receptors, plus signaling agents that affect cell growth or other cellular processes in your culture system leading to optimal performance.
Unique Tools for Optimization
Statistical Approach - A multidimensional approach, based on Design-of-Experiment (DOE) principles, to optimizing medium components. We use several methods to test multiple variables simultaneously, reducing the number of test conditions without a significant loss of information to speed the development process.

Creating better results through a better process:

Defining the measures of success first
Selecting the optimum base medium
Qualifying key raw materials
Verifying performance in the final system
Supporting the process through Quality Systems
Flexibility and accountability in collaboration
Defining the measures of success first:

Cell growth rate
Cell attachment efficiency
Lack of cell aggregation (clumping)
Product quality (e.g., glycosylation)
Maximum cell density
Resistance to agitation forces
Product or virus yield
Product or virus stability
Maintenance of a differentiated or undifferentiated state

Selecting the optimum base medium:

An extensive library of media formulations
Comprehenisve array of specialty media that include serum-free, protein-free, chemically-defined, and animal component-free formulations
Media Platform Technologies:
  CHO
  NSO
  HEK 293
  Per.C6
  Sf9
  Sf21
  Stem cell media (hematopoietic, neural, mesenchymal, skin-derived)

Qualifying key raw materials:

Extensive testing program under cGMP specifications
Complete traceability and full documentation with certificates of analysis, origin and suitability
Multi-compendial (USP/EP) grade components
Products for formulation include various lipid supplements, transferrin substitutes, plant hydrolysates, and recombinant growth factors and hormones that have been specifically designed and optimized for medium formulation
Non-animal derived components include amino acids, lipids, vitamins, and transferrin substitutes

Verifying performance in the final system:

Generation of application data under conditions that represent the final use of the medium in a production environment - e.g., batch, fed batch, and perfusion bioreactors
Validated scale up custom media in cGMP manufacturing processes further supported by method development, method validation and stability studies
Ensured to meet the performance and regulatory demands of the global biopharmaceutical industry

Supporting the process through Quality Systems:

Medium design controls under ISO guidelines
Manufactured in FDA-registered and ISO 9001:2000 certified facility
Process validation
DMFs are on file and can be submitted in support of your product
Complete documentation available (CoAs, CoOs, batch records, etc)

Flexibility and accountability in collaboration:

Flexible contract terms
Defined deliverables
Concise experimental plan (project format) with milestone evaluation points
Timelines meeting and surpassing your expectations against objectives and costs
Secure cell transfer and banking
Scientist exchange at either Sigma-Aldrich R&D center or customer site
Our internal analytical support or external testing services as needed
Faster time to market and better return on investment
