Application Notes
This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.
Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.

Background: Neuropilin-1
Initially found to play an essential role in axon growth and guidance, NRP1 serves as a multifunctional co-receptor for class III semaphorins and heparin-binding members of the VEGF family, participating in regulation of angiogenesis, neuronal development, cell survival, migration and tumor-invasion. Neuropilin-1 has been implicated in viral infections and T-cell activation and is also described as a marker of regulatory T (Treg) cells (3). In COVID-19 infections, studies have shown NRP1 participates in viral infection via NRP1 neutralizing antibodies and binds the SARS-CoV-2 Spike protein, suggesting NRP1 may contribute to viral transport and viral internalization by endocytosis (4).

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.
This product is for research use only and is not approved for use in humans or in clinical diagnosis. Lysates are guaranteed for 6 months from date of receipt.
