Detects mouse GDF-5 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 25% cross-reactivity with recombinant mouse (rm) GDF-6 is observed, and less than 5% cross-reactivity with rmGDF-1, rmGDF-3, rmGDF‑8, rmGDF‑9, recombinant human GDF-11, and rhGDF-15 is observed.
Polyclonal Goat IgG
E. coli-derived recombinant mouse GDF-5 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.
GDF‑5 was detected in immersion fixed frozen sections of mouse embyro (12 d.p.c.) using 15 µg/mL Goat Anti-Mouse GDF‑5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF853) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Growth Differentiation Factor 5 (GDF-5), also known as cartilage-derived morphogenetic protein 1 (CDMP-1), 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 new 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).
