Protein A or G purified from hybridoma culture supernatant
E. coli-derived recombinant mouse GDF-5/BMP-14 Ala376-Arg495 Accession # P43027
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize GDF‑5-induced alkaline phosphatase production in the ATDC5 mouse chondrogenic cell line. The Neutralization Dose (ND50) is typically 2-10 µg/mL in the presence of 3 µg/mL Recombinant Mouse GDF‑5.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Alkaline Phosphatase Production Induced by GDF‑5 and Neutralization by Mouse GDF‑5 Antibody.
Recombinant Mouse GDF‑5 (Catalog # 853‑G5) induces alkaline phosphatase production in the ATDC5 mouse chondrogenic cell line in a dose-dependent manner (orange line). Alkaline phosphatase production elicited by Recombinant Mouse GDF‑5 (3 µg/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse GDF‑5 Monoclonal Antibody (Catalog # MAB8531). The ND50 is typically 2-10 µg/mL.

Growth Differentiation Factor 5 (GDF-5), also known as cartilage-derived morphogenetic protein 1 (CDMP-1) and BMP-14, is a member of the bone morphogenetic protein (BMP) family which belongs to the transforming growth factor beta (TGF‑ beta ) superfamily. GDF-5 is synthesized as a large precursor protein that consists of an N‑terminal 19 amino acid (aa) signal sequence, a 362 aa pro region and a 120 aa C-terminal mature peptide. Mature GDF-5 is a homodimeric protein which contains the characteristic seven conserved cysteine residues. GDF-5, GDF-6 and GDF-7, which share 80‑86% identity, define a subgroup within the BMP family. Like other TGF‑ beta superfamily proteins, GDF-5 is highly conserved across species. At the amino acid sequence level, mature human and mouse GDF-5 are 98% identical. It has been reported that GDF-5 has multiple functions including regulation of myogenesis, regulation of chondrogenesis, bone morphogenesis, and neuron differentiation and survival. GDF-5 response is mediated by the formation of hetero-oligomeric complexes of type I (BMPR-IB) and type II (BMPR-II or Activin R-II) sereine/threonine kinase receptors, and the activation of Smad proteins (Smad 1, 5, and 8).
