In vitro Diagnostic (IVD) Testing Industry Partner

Laboratory scientist in clean suit Leinco Technologies offers large and small-scale antibody production and 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.

Leinco Technologies is ISO certified adhering to the ISO Quality Standard 9001:2015 and is cGMP compliant and subject to numerous annual quality audits. Furthermore, by offering the option to use multiple bioreactor platforms including mammalian cell culture tanks, hollow fiber bioreactors or motion platform cell culture apparatuses small or large-scale production runs are made easy. Because Leinco has developed and validated efficient procedures, uses custom built equipment and manufactures its own cell culture media, we are able to pass on this added value to our partners.
