Biochem/physiol Actions
Clone 3E9 is a mouse monoclonal antibody that specifically detects Reticulocyte binding protein 2b (PvRBP2b) in Plasmodium vivax.
Features and Benefits
His-tagged recombinant fragment corresponding to 1294 amino acids from the N-terminal half of Plasmodium vivax Reticulocyte-binding protein 2 (PvRBP2b).
Preparation Note
Stable for 1 year at -20°C from date of receipt. Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
Analysis Note
Purified mouse monoclonal antibody IgG2a in PBS without azide.
Other Notes
Evaluated by Western Blotting in Plasmodium vivax under non-reducing conditions.
Western Blotting Analysis: A 1:1,000 dilution of this antibody detected purified Reticulocyte-binding protein from Plasmodium vivax (2PvRBP2b) under non-reducing conditions.

Reticulocyte-binding protein 2 (UniProt: Q00799; also known as PvRBP2) is encoded by the RBP-2 (also known as RBP2) gene in Plasmodium species. PvRBP2b is an alpha-helical protein, comprising 10 alpha-helices and two very short antiparallel beta-sheets, each comprising two beta-strands. It plays a critical role in reticulocyte recognition and invasion by Plasmodium vivax. It is synthesized with a signal peptide (aa 1-21), a large extracellular domain (aa 22-2805), a short transmembrane domain (aa 2806-2826), and a cytoplasmic tail (aa 2827-2867). Plasmodium vivax is shown to preferentially invade reticulocytes that express high levels of transferrin receptor 1 (TfR1). PvRBP2b is expressed during the late-stage of Plasmodium vivax and its binding has been shown to directly correlate with the levels of TfR1 on reticulocyte surface. Treatment of reticulocytes with trypsin or chymotrypsin can cleave TfR1 from reticulocyte surface and prevent PvRBP2b binding. Clone 3E9 is shown to inhibit reticulocyte binding and block the entry of Plasmodium vivax into reticulocytes. This antibody binds to the side of the N-terminal domain of PvRBP2b to a region localized between helices alpha 4, 5 and 6. (Ref.: Gruszczyk, J., et al. (2018).
