Amphiregulin Protein, Mouse

Customer Review

Based on 1 Customer Validation

Amphiregulin Protein, an EGFR ligand, acts as an autocrine growth factor and mitogen for diverse cells, including astrocytes, Schwann cells, and fibroblasts. Engaging with CNIH in its immature stage, Amphiregulin's EGFR activation emphasizes its vital role in regulating cell growth and orchestrating various cellular functions across different cell types. Amphiregulin Protein, Mouse is the recombinant mouse-derived Amphiregulin protein, expressed by E. coli , with tag free.

Biological Activity

Description

Amphiregulin Protein, an EGFR ligand, acts as an autocrine growth factor and mitogen for diverse cells, including astrocytes, Schwann cells, and fibroblasts. Engaging with CNIH in its immature stage, Amphiregulin's EGFR activation emphasizes its vital role in regulating cell growth and orchestrating various cellular functions across different cell types. Amphiregulin Protein, Mouse is the recombinant mouse-derived Amphiregulin protein, expressed by E. coli , with tag free.

Background

Amphiregulin, a ligand for the EGF receptor (EGFR), functions as both an autocrine growth factor and a mitogen for a diverse array of target cells, such as astrocytes, Schwann cells, and fibroblasts. Its impact spans cellular proliferation, and during its immature precursor stage, Amphiregulin engages in interactions with CNIH. This versatile ligand's capacity to activate EGFR underscores its crucial role in regulating cell growth and underscores its significance in orchestrating various cellular functions across different cell types.

Verified Bioactivity

Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells. The ED50 for this effect is <20 ng/mL.
