Scientific Data Images for Mouse/Rat Plexin A3 Antibody

Plexin A3 in Mouse Spinal Cord.

Plexin A3 was detected in immersion fixed frozen sections of 13 d.p.c. embryonic mouse spinal cord using Goat Anti-Mouse Plexin A3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4075) at 10 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).

Plexin A3 in Rat Brain (Cortex).

Plexin A3 was detected in immersion fixed paraffin-embedded sections of rat brain (cortex) using Goat Anti-Mouse/Rat Plexin A3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4075) at 10 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (VC004). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to neuroglia. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

Background: Plexin A3

Plexin A3 (also known as SEX) is a 220 kDa member of the Plexin A subfamily of semaphorin receptors. Mature mouse Plexin A3 is predicted to be an 1853 amino acid (aa) type I transmembrane glycoprotein that contains a 1202 aa extracellular domain (ECD) and a 629 aa cytoplasmic region. The ECD contains one semaphorin domain (aa 34-473), three plexin-semaphorin-integrin (PSI) domains (aa 492-830), and four lg-like plexin-transcription factor (IPT) repeats (aa 841-1209). Plexin A3 interacts with neuropilins 1 and 2, and binds class 3 semaphorins. Over aa 35-150, mouse Plexin A3 is 99% and 97% aa identical to rat and human Plexin A3, respectively.
