Scientific Data Images for Human Neuronal Pentraxin R/NPTXR Antibody

Detection of Human Neuronal Pentraxin R/NPTXR antibody by Simple WesternTM.

Detection of Human Neuronal Pentraxin R/NPTXR by Simple WesternTM.

Simple Western lane view shows lysates of U-87 MG human glioblastoma/astrocytoma cell line and human hippocampus tissue, loaded at 0.2 mg/mL. A specific band was detected for Neuronal Pentraxin R/NPTXR at approximately 66 kDa (as indicated) using 20 µg/mL of Sheep Anti-Human Neuronal Pentraxin R/NPTXR Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4414) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Detection of Neuronal Pentraxin R/NPTXR in Hippocampus.

Neuronal Pentraxin R/NPTXR was detected in immersion fixed paraffin-embedded sections of Hippocampus using Sheep Anti-Human Neuronal Pentraxin R/NPTXR Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4414) at 10 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Sheep IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC006). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in neurons.

Background: Neuronal Pentraxin R/NPTXR

NPTXR (Neuronal Pentraxin Receptor; also NPR) is a 65 kDa, type II transmembrane glycoprotein that binds Neuronal Pentraxins 1 and 2. It is expressed on cerebellar Purkinje and granule cells, and hippocampal neurons of the CA1, CA3 and dentate gyrus regions. Human NPTXR is 499 amino acids (aa) in length. It contains a two aa cytoplasmic tail, a 21 aa transmembrane segment, and a 476 aa extracellular region with one Pentraxin domain (aa 295‑499). One alternate start site exists at Met12, and a 55 kDa soluble form (possibly beginning at Gln56) may be generated by proteolytic cleavage. Over aa 24‑499, human NPTXR is 87% aa identical to mouse NPTXR.
