Short Description

Plexin domain containing protein 2 (PLXDC2), a cell surface transmembrane protein, is expressed in many tissues including haemotopoeitc stem cells, neural stem cells, pluripotent stem cells, and tumor cells. PLXDC2 may play an important role in neuronal growth, stem cell development, angiogenesis, and cancer cell growth. Recently PLXDC2 was reported a good cell surface marker as human haemotopoetic stem cells (1).

PLXDC2 has been reported as a receptor for pigment epithelium derived factor (PEDF) (2) or as an activating ligand for adhesion G-protein coupled receptor D1 (Adgrd1) (3). Also PLXDC2 was thought as a novel interaction partner and an entry receptor for rhesus monkey rhadinovirus (RRV) 4). The gene expression level of PLXDC2 was elevated in the peripheral blood of stroke patients (5) or in mouse bone marrow-derived macrophages in response to Helicobacter pylori (6). The protease BACE1 (β-Site APP Cleaving Enzyme), a major drug target in Alzheimer's disease, cleaves the amyloid precursor protein (APP) as well as PLXDC2 as one of several other substrates (7).

Cell Culture Products
Microtiter wells were coated with human PLXDC2-ECD (extracellular domain, truncated a transmembrane domain from PLXDC2) at 5 ug/mL. Anti-PLXDC2 (4G3) rabbit mAb Biotin Conjugate (Cat#2535) was diluted at 1 ug/mL and 0.1 ug/mL. Anti-PLXDC2 (4G3) rabbit mAb Biotin Conjugate show very specific binding to human PLXDC2-ECD antigen.
Cell Culture Products
A sandwich ELISA was performed using anti-PLXDC2 specific rabbit mAb: 3B8 (Cat#XXXX) as a capture antibody and 4G3-biotin (Cat#2535) as a detection antibody. Human PLXDC2-ECD#2631 was serially diluted 1:1 starting at 5 ug/mL. Anti-PLXDC2 rabbit mAb 3B8 and 4G3-biotin detected hPLXDC2-ECD antigen at very high sensitivity as low as 100 pg/mL.
