| Mannose-BSA
Mannose-BSA is an important organic intermediate that combines the properties of mannose and bovine serum albumin, which is of unique value in the field of scientific research, and can be used as a key substance in a variety of organic synthesis reactions. Mannose is an important monosaccharide that binds specifically to mannose receptors (e.g., CD206 receptors on dendritic cells and macrophages), and therefore has a wide range of applications in immunomodulation and targeted drug delivery. BSA is a protein carrier that is commonly used for biocoupling, and its abundant surface amino groups can covalently bind to mannose to form a mannose-BSA complex. |
