QUALITY CONTROL

All purified antibodies/proteins and conjugates will be analyzed by electrophoresis, specificity testing, and/or chromatography techniques (FPLC or HPLC) to meet customer defined parameters. Once these specifications are met, the product will be stored or shipped with a certificate of analysis (COA) stating all tested customer-specified parameters of product quality were met. This service provides the customer with traceability and lot-to-lot consistency during the production of your components.

Affinity Life Sciences provides cost effective cell culture services for the production of recombinant proteins using mammalian cell lines (CHO and others) and bacterial cell lines (E.Coli or others). We can also provide development of monoclonal antibodies or your clone can be provide to Affinity for antibody production. Affinity also provides growth of microorganisms for quality control testing of in-process or production materials.

Using various production methods such as roller bottles, hollow fiber, and WAVE Bioreactor, Affinity Life Sciences can optimize production and develop specific formulations and conditions for your cell line to improve performance and quality.
