Digoxigenin is a steroid isolated from Digitalis plants and frequently used for biodetection purposes. This BSA-digoxigenin conjugate is designed with a flexible linker to allow easy interaction between digoxigenin and other detection molecules, and is synthesized at CellMosaic for our customers' usage in immunization or immunoassay. A linker is first added to digoxigenin site-specifically via its OH group and then digoxigenin is labeled at the surface amines of BSA. BSA has a high amount of digoxigenin loaded without any additional aggregation. The final conjugate is lyophilized from phosphate buffered saline containing sugar-based stabilizer for easy shipping and storage. 

The product is sold as either 1 vial of 1 mg (Cat# CM52107_1MG) or 5 vials of 1 mg (Cat# CM52107_5MG). For bulk orders, please contact us for a quote.
