Shipping conditions update: ambient shipping
This product will be delivered at ambient temperature instead of chilled – this is by design. Extensive stability testing confirmed that our products are suitable for shipment under ambient conditions and maintain expected quality.
Why the change?
It’s part of our commitment to more sustainable packaging solutions, with ambient deliveries using eco-friendly materials such as recyclable cardboard instead of polystyrene.
What you need to know
Ambient shipments come clearly marked on the delivery note.
No ice will be included in ambient shipments, but mixed orders (ambient and cold-chain items) will still arrive with ice packs to protect temperature-sensitive products.
Warranty coverage remains fully valid, aligned with our validated shipping method.
Please store the product as per the datasheet instructions upon receipt.

Neuropilin-1 also known as NRP1 is a transmembrane protein with a significant role in the nervous and vascular systems. It has a molecular mass of approximately 130 kDa. Neuropilin-1 expression occurs broadly in tissues including neurons endothelial cells and tumor cells. Its structure includes a large extracellular domain that binds various ligands mediating several cellular functions. Neuropilin-1 is sometimes targeted in experiments using methods like neuropilin-1 ELISA and PE immunofluorescence to study its distribution and function in different tissues.
Biological function summary
Neuropilin-1 serves as a co-receptor for both the Vascular Endothelial Growth Factor (VEGF) and Semaphorin family proteins. It plays an important role in processes such as angiogenesis axonal guidance and the immune system. Neuropilin-1 does not function alone; it forms complexes with neuropilin-2 and other receptors like Plexin and VEGFR enhancing signal transduction pathways for angiogenesis and neuronal development. This involvement allows cells to respond appropriately to their environment especially during organismal development and repair processes.
Pathways
Neuropilin-1 facilitates interactions within the VEGF and Semaphorin pathways. In the VEGF pathway Neuropilin-1 enhances binding and signaling efficiency with VEGF closely working alongside VEGFR to promote endothelial cell survival migration and new blood vessel formation. In the Semaphorin pathway Neuropilin-1 interacts with Plexins mediating neuronal pathfinding and axonal growth. These interactions highlight Neuropilin-1's adaptive capabilities in various physiological processes critical for system development.
Neuropilin-1 is linked to pathological conditions like cancer and cardiovascular diseases. Neuropilin-1 overexpression is frequently observed in tumors driving cancer progression through enhanced angiogenesis and tissue invasion closely interacting with proteins like VEGF-A. In cardiovascular disease Neuropilin-1 contributes to abnormal blood vessel formation and stability. By studying Neuropilin-1 and other biomarkers like CD304 FITC researchers aim to develop therapeutic strategies targeting its role in these diseases.
