What TdB Labs AB does
TdB Labs AB is a privately held Swedish biotechnology company headquartered in Uppsala, founded in 1991 by Tony de Belder, a recognized pioneer in dextran chemistry. The company specializes in the development, manufacture, and supply of dextran and polysaccharide derivatives — including fluorescent conjugates (FITC, TRITC, ATTO, the proprietary Antonia Red™ dye, and Eosin Y), non-fluorescent derivatives, and pH-sensitive probes — for use in life science research, pharmaceutical development, and medical device manufacturing. Its technology base rests on proprietary conjugation chemistry, notably a lysine-dextran conjugation technique and a thiocarbamoyl linkage, alongside proprietary dye development including Antonia Red™.
The company monetizes through three revenue streams: (1) catalog sales of standardized dextran and dye products, (2) customized product development for OEM and research customers, and (3) analytical services. Go-to-market combines a direct e-commerce webshop for smaller and international buyers with regional distributor partnerships — most recently BIOZOL in Germany from June 2025, extending DACH-region reach — and direct institutional sales. A named anchor customer is European Medical Contract Manufacturing B.V. (EMCM), which incorporates TdB Labs' dextran into a CE-marked medical device. The firm has held ISO 9001 certification since August 2015 and was recognized as a "Vinnare Småföretag" winner in the Bona Postulata 2020 awards, reflecting its standing as an established, quality-certified Swedish small business.
TdB Labs operates as a focused niche manufacturer in a specialized segment of life science reagents. Its competitive position is built on three decades of accumulated polysaccharide chemistry expertise, proprietary dye and conjugation IP, and a small but global customer footprint spanning academic, industrial, and regulated medical device end markets. The absence of disclosed funding rounds, headcount figures, or revenue data limits external visibility into scale, but the breadth of catalog, the OEM customer reference, and the recent channel expansion indicate a stable, commercially active specialty reagent business rather than an early-stage venture.
