Sample

ELISA

This antibody functions as an ELISA capture antibody when paired with Mouse Anti-Human GDF‑11/GDF‑8 Monoclonal Antibody (Catalog # MAB19582 or Catalog # MAB19582R).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human Granzyme A DuoSet ELISA Kit (Catalog # DY2905-05) 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 GDF‑11/BMP‑11 ELISA Standard Curve. Recombinant Human GDF-11/BMP-11 protein was serially diluted 2-fold and captured by Mouse Anti-Human GDF-11/BMP-11 Monoclonal Antibody (Catalog # MAB19584) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human GDF-11/GDF-8 Monoclonal Antibody (Catalog # MAB19582or Catalog # MAB19582R) 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: GDF-11/BMP-11

Growth Differentiation Factor 11 (GDF-11), also known as BMP-11, is a member of the TGF-beta superfamily and is highly related to GDF-8. GDF-11 encodes a 407 amino acid (aa) prepropeptide which contains a signal sequence for secretion and an RXXR proteolytic processing site to yield a 109 aa residue carboxy-terminal mature protein (1). Mature GDF-11 contains the canonical 7-cysteine motif common to other TGF-beta superfamily members; however, like the TGF-beta s, Activins and GDF-8, GDF-11 also contains one extra pair of cysteine residues. At the amino acid sequence level, mature human, mouse, rat and chicken GDF-11 are 99‑100% identical. GDF-11 and GDF-8 share 90% amino acid sequence identity within the mature protein. As detected by in situ hybridization, GDF-11 is expressed in diverse regions of the mouse embryo: tailbud, somitic precursors, limbs, mandibular and branchial arches, dorsal neural tube, odontoblasts, nasal epithelium, and particular regions of the brain (1, 2). Likewise, a targeted deletion of GDF-11 in mice results in a spectrum of abnormalities including palatal malformation, vertebral defects, elongated trunks with a reduced or absent tail, missing or malformed kidneys, and an increased number of neurons in the olfactory epithelium (2-5). An intriguing finding in the knockout mice was that the trunk elongation was due to an increase in the number of thoracic vertebrae (4). This implicates GDF-11 as the first secreted factor to influence the specification of segmental identity in vertebrates (3). In fact, GDF-11 does regulate expression of segmental transcription factors, the Hox genes (6). GDF-11 signals through the Activin type II receptors and induces phosphorylation of Smad2 to mediate axial patterning (7). Despite the strong expression in the limb throughout development, no limb abnormalities were found in the knockout mice. However, in vitro micromass studies indicate that GDF-11 inhibits myogenic and chondrogenic cell differentiation and may impact formation and development of the limb skeleton (6).
