Neuropilin-1 Protein

Neuropilin-1 Protein Overview

Neuropilin-1 reagents

NRP1 is a membrane-bound coreceptor to a tyrosine kinase receptor for both vascular endothelial growth factor (VEGF; 192240) and semaphorin (see SEMA3A; 603961) family members. NRP1 plays versatile roles in angiogenesis, axon guidance, cell survival, migration, and invasion.

Neuropilin-1 Protein Interaction

Recombinant Neuropilin-1 Protein Feature

Neuropilin-1 Protein, Human, Recombinant (His Tag)

High Purity
> 95 % as determined by SDS-PAGE
Low Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
High Activity
1. Using the Octet RED System, the affinity constant (Kd) of NRP1-his bound to biotinylated human VEGF165 was 25nM. 2. Measured by its binding ability in a functional ELISA. Immobilized NRP1-His (Cat:10011-H08H) at 10 μg/mL (100 μL/well) can bind VEGF165/Biotin (Cat:11066-HNAH), the EC50 of VEGF165/Biotin (Cat:11066-HNAH) is 18-40 ng/mL.
