Neuropilin-1 (UniProt: O14786; also known as Vascular endothelial cell growth factor 165 receptor, CD304) is encoded by the NRP1 (also known as NRP, VEGF165R) gene (Gene ID: 8829) in human. Neuropilins are highly conserved, non-tyrosine kinase, single-transmembrane glycoproteins that serve as co-receptors for various molecules, including semaphorins and vascular endothelial growth factors (VEGF). Neuropilin-1 is a single-pass type I, homodimeric, membrane glycoprotein that is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off to generate the mature form that contains a long extracellular domain (aa 22-856), a transmembrane domain (aa 857-879), and a cytoplasmic domain (aa 880-923). It acts as a receptor involved in the development of the cardiovascular system, angiogenesis, and formation of certain neuronal circuits. It is also reported to mediate the chemorepulsant activity of semaphorins. Neuropilin-1 has four well conserved domains: CUB (a1/a2; aa 27-141 and 147-265) domain, F5/8 (b1/b2; aa 275-424 and 431-583) domain, MAM domain (aa 645-811), and another domain that contains a transmembrane and a short cytoplasmic region. CUB domains mediate binding to semaphorins, while the tandem F5/8 domains are responsible for VEGF and heparin binding and recognizes a C-end role (CendR) motif R/KXXR/K on its ligands. The presence of the CUB (a1a2) domain is reported to enhance VEGF165 binding to F5/8 (b1b2) domain. The MAM domain is reported to mediate semaphorin signal transduction to Plexin-A. Neuropilin-1 has been recognized as an additional cellular mediator that facilitates the entry of SARS-CoV-2 into host cells. It binds to furin-cleaved spike protein and significantly potentiates SARS-CoV-2 infectivity. This effect can be blocked by monoclonal antibodies against the extracellular F5/8 (b1/b2) domain of Neuropilin-1 or with selective Neuropilin antagonists that bind to CendR binding b1 pocket. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions

Clone 1H21 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Neuropilin-1. It targets an epitope within 19 amino acids from the C-terminal region.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Preparation Note

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
