Product Usage Information

Application Dilution
Immunofluorescence (Frozen) 1:50 - 1:200

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity/Sensitivity

GPNMB (E7U1Z) Horse Chimeric Monoclonal Antibody recognizes endogenous levels of total GPNMB protein. This antibody does not cross-react with human GPNMB protein.

Source / Purification

This recombinant chimeric antibody is engineered from GPNMB (E7U1Z) Rabbit mAb #90205 according to animal-free protocols. The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody but contains a horse-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies.

The parent antibody, GPNMB (E7U1Z) Rabbit mAb #90205, is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of mouse GPNMB protein.

Description

This Cell Signaling Technology® antibody retains the antigen-binding Fab regions of the original parent host sequence from which it is engineered. This antibody is expected to exhibit the same species cross-reactivity as GPNMB (E7U1Z) Rabbit mAb #90205.

Background

Glycoprotein non-metastatic gene B (GPNMB) is a type I transmembrane glycoprotein overexpressed in many types of cancer. The GPNMB glycoprotein is involved in many physiological processes, including mediating transport of late melanosomes to keratinocytes (1), regulating osteoblast and osteoclast differentiation and function (2), stimulating dendritic cell maturation, promoting adhesion of dendritic cells to endothelial cells (3), enhancing autophagosome fusion to lysosomes in tissue repair, and regulating degradation of cellular debris (4,5).

While typical GPNMB expression is seen in tissues including skin, heart, kidney, lung, liver, and skeletal muscle (3,6), research studies show elevated GPNMB expression often contributes to the metastatic phenotype in numerous cancers (reviewed in 7). GPNMB is typically localized to intracellular compartments in normal cells (1,8), but investigators found it primarily on the cell surface of tumor cells (9,10). Differential localization and expression, and the role of GPNMB as a tumor promoter in many cancer types make this protein a viable therapeutic target (11).

The GPNMB ectodomain can be cleaved by matrix metalloproteinases and shed from the cell surface (12). Research studies identify the sheddase ADAM10 as one peptidase responsible for cleavage of the GPNMB ectodomain at the surface of breast cancer cells. Shedded GPNMB ectodomains may promote angiogenesis by inducing endothelial cell migration (13).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).
