Product Information
Bacterial heparinase I, also known as heparin lyase I, is a enzyme cloned from Bacteroides thetaiotaomicron and expressed in E. coli. It exhibits activity toward both heparin and the highly sulfated domains of dermatan sulfate. This reaction yields oligosaccharide products containing unsaturated uronic acids, which can be detected by UV spectroscopy at 232 nm.
Bacterial heparinase I cleaves the glycosidic bonds between N-sulfated hexosamine residues and 2-O-sulfated iduronic acid residues, as well as between 2-O-sulfated glucuronic acid residues. The 2-O-sulfation of uronic acid residues is essential for the activity of bacterial heparinase I, whereas 6-O-sulfation of GlcNS does not inhibit enzyme activity.
Product Applications
Heparinase I can be used to study the mechanisms of heparin synthesis, degradation, and metabolism. In vitro, it can be employed to degrade heparin, thereby facilitating a deeper understanding of its biological activities. Heparinase I is also applicable for the preparation of low-molecular-weight heparins (LMWHs).

Shark single-domain antibody

By innovatively reengineering biological scaffolds, the single-domain antibody products developed from shark-derived natural heavy-chain antibodies offer several advantages over conventional antibodies, including smaller molecular size, enhanced stability, superior tissue penetration, and reduced immunogenicity. These products are applicable in areas such as targeted drug development, in vitro diagnostic reagent design, and biopharmaceutical research, while also providing customized development and large-scale production services. This product can be tailored to generate single-domain antibodies with diverse antigen specificities, supporting end-to-end services from antibody screening through to large-scale purification. The resulting antibodies meet biopharmaceutical R&D and manufacturing‑grade purity standards, and corresponding quality‑control reports are available. Currently, we have established a mature platform for shark immunization, phage‑display library construction, and screening, enabling rapid generation of high‑affinity, highly specific single-domain antibody clones against a wide range of target antigens. We can flexibly adjust development timelines to align with clients’ project schedules, ensuring efficient delivery.
