Detects mouse NELL1 in direct ELISAs and Western blots. In direct ELISAs, approximately 25% cross-reactivity with recombinant human NELL1 is observed and approximately 10% cross-reactivity with recombinant mouse NELL2 is observed.
Polyclonal Sheep IgG
Chinese hamster ovary cell line CHO-derived recombinant mouse NELL1 Arg17-Asn810 Accession # Q2VWQ2
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.
Detection of Mouse NELL1 by Western Blot.
Western blot shows lysates of Neuro‑2A mouse neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Mouse NELL1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7109) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for NELL1 at approximately 110 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
NELL1 in Mouse Embryo.
NELL1 was detected in immersion fixed frozen sections of mouse embryo (13 d.p.c.) using Sheep Anti-Mouse NELL1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7109) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to neurons in the spinal cord. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

NELL1 (neural EGF-like like protein 1) is an 89 kDa (predicted) member of the EGF-like domain containing family, Laminin G/N-TSP1/Pentraxin gene superfamily of molecules. When secreted, NELL1 exists as a phosphoglycoprotein that can add as much as 50 kDa to the calculated MW. NELL1 has restricted expression, being limited to pre-B cells and osteoblasts, where it apparently promotes osteoblast maturation and bone formation. In tumors, it is found in neuroblastoma-derived cells. NELL1 is both secreted and retained intracellularly where it is phosphorylated by PKC. The mouse NELL1 precursor is 810 amino acids (aa) in length. It contains a 16 aa signal sequence plus a 794 aa mature region. The mature region possesses an N-terminal TSP domain (aa 81-230), two VWFC domains (aa 271-390), six consecutive EGF-like domains (aa 391-631), and three additional C-terminal VWFC domains (aa 632-807). Secreted NELL1 forms a 400-420 kDa noncovalent homotrimer. Over aa #17-810, mouse NELL1 shares 98% and 93% aa identity with rat and human NELL1, respectively.
