What CANDOR Bioscience GmbH does
CANDOR Bioscience GmbH is a German specialty life-sciences company founded in 2004 and headquartered in Wangen im Allgäu, where it operates its own ISO 9001:2015- and ISO 13485:2021-certified manufacturing facility. The company develops and produces more than 50 premium buffer solutions, stabilizers, and surface blockers designed to eliminate interference in immunoassays, including HAMA (human anti-mouse antibodies), rheumatoid factors, nonspecific binding, cross-reactivities, and matrix effects. Its proprietary platforms include the LowCross-Buffer family (with MILD and STRONG affinity-discrimination variants), Assay Defender for HAMA and interference blocking, Liquid Plate Sealer for coating stabilization, and the LowCross HRP-Stab combined diluent/storage solution.
The company serves three primary customer segments: IVD kit manufacturers (for commercial production of human, veterinary, food, and environmental diagnostics), pharmaceutical companies (for pre-clinical and clinical bioanalytical immunoassays under EMA/FDA requirements), and research laboratories (for ELISA, Western Blot, immunohistochemistry, protein arrays, and immuno-PCR). Beyond the core buffer portfolio, CANDOR has expanded into workflow-format products including ReadyTector (all-in-one Western blot detection) and SafetyTector (low-cost safety solution for antigen rapid tests), and offers fee-for-service assay development, ELISA optimization, stability testing, and commissioned buffer production from 1 liter to 2,000 liters per batch.
CANDOR distributes products through a network of more than 40 channel partners across 20+ countries in Europe, Asia-Pacific, North America, the Middle East, and Africa, and serves more than 1,000 customers in over 50 countries overall. In January 2025, CANDOR was acquired by Medix Biochemica Group, integrating the company into a larger global diagnostics raw materials platform while preserving the CANDOR brand, product line, and German manufacturing base.
