MA1-06821 detects large heparan sulphate proteoglycan in human, mouse, bovine, cod, wolffish, and rat samples.
MA1-06821 has sucessfully been used in Western blotting, immunocytochemistry, immunoprecipitation, and immunohistochemistry procedures. By Western blot it detects a >400 kDa band representing large HSPG.
The MA1-06821 immunogen is a high molecular mass material derived from the Engelbreth-Holm-Swarm (EHS) tumor matrix containing laminin, entactin and HSPG.
Proteoglycans are macromolecules consisting of a variety of core proteins with covalently attached one or several polysaccharide chains of the glycosaminoglycan type (heparan sulphate, heparin, chondroitin sulphate, dermatan sulphate or keratan sulphate). At least two forms of basement membrane heparan sulphate proteoglycan (HSPG) have been identified. One with a large core protein (>400 kD) and one with a small core protein (~30 kD). The large HSPG is probably the most abundant basement membrane proteoglycan. It is located predominantly in the lamina lucida, where it forms clustered aggregates and interacts with other basement membrane components to form the matrix. In addition, it also plays a critical role in attachment of cells to the basal membrane via integrin receptors.
