Detects mouse RGM-A in direct ELISAs and Western blots. In direct ELISAs, less than 15% cross-reactivity with recombinant human RGM-A and recombinant chicken RGM-A is observed and less than 1% cross-reactivity with recombinant mouse (rm) RGM-B and rmRGM-C is observed.
RGM‑A in Mouse Embryo. RGM‑A was detected in immersion fixed frozen sections of mouse embryo (13 d.p.c) using Goat Anti-Mouse RGM‑A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2458) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to retina and developing neurons in cross-section of the developing eye. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Mouse repulsive guidance molecule (RGM-A) is a 33 kDa GPI-linked member of an expanding RGM-related family of neuronal and muscle-expressed membrane proteins (1). It is synthesized as a 454 amino acid (aa) preproprotein that contains a 47 aa signal sequence, a 122 aa N-terminal prosegment, a 258 mature region and a 27 aa C-terminal prosegment (2, 3). The N-terminal prosegment contains an RGD tripeptide and the molecule’s only two potential N-linked glycosylation sites. The mature segment shows an abbreviated von Willebrand factor domain. Proteolytic processing occurs at an aspartic acid-proline bond, creating a predicted 32 kDa mature region (2). The mature region of mouse RGM-A is 93% and 87% aa identical to human and chick mature region RGM-A, respectively. When compared to mouse RGMb and c, the mature region of mouse RGM-A shows 77% and 76% aa identity, respectively (2, 3). Recombinant chick RGM has been reported to induce collapse of temporal but not nasal growth cones, and to repel temporal retinal axons in vitro. This suggests a role in the development of the retina-superior colliculus connection. In mice, however, this activity is not so obvious, and thus its function in this system is uncertain (3). Alternatively, in mice, RGM-A is said to be needed for neural tube closure (3). And in a mouse culture system, chick RGM-A is reported to be responsible for the layered segmentation of of entorhinal cortical projections to the hippocampus (4). The receptor for RGM is reported to be neogenin (5, 6).
