Applications

Recommended Concentration

Sample

ELISA

This antibody functions as an ELISA capture antibody when paired with Mouse Anti-Human Gremlin Monoclonal Antibody (Catalog # MAB5190).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human Gremlin DuoSet ELISA Kit (Catalog # DY5190-05) for convenient development of a sandwich ELISA.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Human Gremlin ELISA Standard Curve. Recombinant Human Gremlin protein was serially diluted 2-fold and captured by Mouse Anti-Human Gremlin Monoclonal Antibody (Catalog # MAB51901) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human Gremlin Monoclonal Antibody (Catalog # MAB5190) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: Gremlin

Gremlin was identified in a Xenopus expression-cloning screen as a dorsalizing factor that can induce a secondary axis. A rat homolog, called Drm, was identified as a cDNA that was downregulated in v-mos transfected cells. Gremlin/Drm belongs to the DAN family of secreted glycoproteins that are BMP antagonists. Other members of the family include: Cerberus, Dante, PRDC, Caronte, and DAN. DAN family members share a cysteine-rich domain that is structurally related to the cysteine-knot motif found in TGF-beta superfamily ligands. In vitro, Gremlin/Drm binds BMP-4 and BMP-2 indicating that it might interfere with BMP signaling. Gremlin/Drm acts as a BMP-2/4 antagonist in a variety of tissues and developmental processes including: Xenopus animal cap explants, chick limb bud outgrowth and chondrogenesis, murine lung branching morphogenesis, and osteogenic differentiation of mouse myoblasts and bone marrow stromal cells. In addition, expression of Gremlin/Drm has been shown to be downregulated in a wide range of human cancer cell lines. Mouse, human, chick and Xenopus homologs of Gremlin share over 80% amino acid identity. It is likely that various DAN family members and other BMP antagonists including Noggin, Chordin, Follistatin and TSG can selectively antagonize the activities of different subsets of TGF-beta superfamily ligands.
