In vitro Diagnostic (IVD) Testing Industry Partner

Leinco Technologies offers large and small-scale IVD antibodies and protein production at lower costs due to a highly experienced scientific staff and state of the art biotechnology facility. Manufacturing of proteins and antibodies at Leinco is confined to class 10,000 dedicated cleanroom suites all located in St. Louis Missouri. Each product starts off in cell culture where the seed culture is prepared for transfer to bioreactors operated in dedicated cleanroom suites. Separate and dedicated downstream suites are used to clarify and concentrate bioreactor harvest and prepare it for purification using appropriate chromatography methods. Our extensive bioanalytics department assures that each active diagnostic component manufactured meets the required purity and functional specifications established for the product and set by the customer.

Cryo Storage Facility and Hybridoma Cell Line Optimization

In addition to IVD antibodies and protein production, Leinco offers the preparation of highly optimized master cell banks (MCB’s) and working cell banks (WCB’s) with offsite storage capabilities. Cell line optimization and banking is an important component to achieve lot to lot consistency and long-term production requirements. Testing is performed on each cell bank to assure cells are mycoplasma negative and free of other adventitious agents.
