IVD Antibodies In Vitro Diagnostics (IVD) Antibodies are crucial in detecting diseases, infections, and various medical conditions. Utilized in laboratories, agriculture, healthcare settings, and even at home, these tests play a vital role in disease screening, therapeutic monitoring, and drug screening. Our IVD antibodies are important components of diagnostic immunoassays, particularly in techniques such as lateral flow and sandwich ELISA. We develop high-quality, low cross-reactivity IVD antibody pairs that are designed to enhance the accuracy of IVD kits. Since 1992, our commitment to innovation and quality has made us leaders in IVD antibody development, crafting products that meet the highest standards for reliability and precision. Explore our diverse portfolio of IVD antibodies and other critical IVD raw materials for diagnostics, each designed to advance your diagnostic and research endeavors with unmatched excellence.

Lateral flow development Scale-up and manufacturing of clinical biologicals ELISA manufacturing
High-Quality, Optimized Cell Line Development and Production Process
Cell Line Development and Cell Culture: Each product starts off in cell culture where the seed culture is prepared for transfer to bioreactors operated in dedicated cleanroom suites. Leinco develops and manufactures its own cell culture media for complete control over the production process. Separate and dedicated downstream suites are also used to clarify and concentrate bioreactor harvest.
Scale-Up Production: Leinco utilizes class 10,000 biotechnology cleanrooms for manufacturing antibodies and proteins. Multiple bioreactor platforms are available for mammalian cell culture and protein production runs including small scale static roller bottle production, WAVE bioreactor(™) systems, hollow fiber bioreactor systems (developed in-house), motion platform cell culture apparatuses, or tank bioreactor systems for continuous perfusion harvesting.
Purification & Chromatography Methods: Using validated, efficient procedures and custom-built equipment, our Purification Department optimizes antibodies and proteins to meet product specifications.
Quality Control & Bioanalytics: Analytical tests are conducted to assure each active diagnostic component manufactured meets the required purity and functional specifications established for the product and set by the customer.
