This HOST5DS monoclonal antibody recognizes human GPNMB also known as Osteoactivin, DC-HIL and HGFIN. This type-1 transmembrane glycoprotein was described independently as a bone development factor, tumor related molecule, neurokinin, and immune regulator. Expressed on macrophages and dendritic cells, GPNMB is a ligand for proteoglycan Syndecan-4 (SD-4), which is found on T cells, and is known to inhibit their activation and proliferation. Hence, surface expression of GPNMB by myeloid cells may be indicative of their tolerogenic properties. Various cancers express GPNMB, and it is suspected to help in immune evasion. Treatment with IL-10 and various immunosuppressive drugs (e.g., dexamethasone) upregulate GPNMB on macrophages and dendritic cells. THP-1 and U937 cell lines constitutively express GPNMB. GPNMB may also be secreted.

The HOST5DS antibody will work on paraformaldehyde-fixed and permeabilized cells, and can be used for intracellular staining. Please, note that enzymatic tissue dissociation may reduce the amount of surface GPNMB, and thereby negatively impact the brightness of the staining.
