Product details:
Abcam's Amphiregulin (AREG) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an
in vitro
enzyme-linked immunosorbent assay for the quantitative measurement of Human Amphiregulin in plasma, and cell culture supernatants. (Human Amphiregulin concentration is pretty low in normal plasma, it may not be detected in this assay).
This assay employs an antibody specific for Human Amphiregulin coated on a 96-well plate. Standards and samples are pipetted into the wells and Amphiregulin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Amphiregulin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Amphiregulin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
We have not been able to detect endogenous Human Amphiregulin in normal serum with ab99975, only in serum spiked with Human Amphiregulin.
Optimisation may be required with urine samples.

'Amphiregulin' also known as 'AREG' or 'Amphiregulin protein' is a member of the epidermal growth factor (EGF) family. It is a 252 amino acid protein with a predicted mass of approximately 27-29 kDa. Amphiregulin shows expression in various tissues including epithelial cells fibroblasts and immune cells. This protein functions as a ligand for the EGF receptor (EGFR) leading to receptor dimerization and subsequent activation of downstream signaling pathways.
Biological function summary
'Amphiregulin' plays a critical role in cell proliferation differentiation and tissue remodeling. It is not part of a constitutive complex but rather exerts its effects through interaction with EGFR a receptor tyrosine kinase. Amphiregulin contributes significantly to mammary gland development and has a notable role in wound healing. Beyond its developmental roles Amphiregulin can impact immune modulation and inflammation processes.
Pathways
'Amphiregulin' significantly contributes to the mitogen-activated protein kinase (MAPK) and phosphoinositide 3-kinase (PI3K) pathways. These pathways influence cell survival growth and proliferation. Amphiregulin interacts with EGFR and by extension has relationships with other EGFR ligands such as EGF and transforming growth factor-alpha (TGF-alpha). These pathways underline the importance of Amphiregulin in maintaining cellular functions and responding to external stimuli.
'Amphiregulin' has strong associations with cancer and asthma. Overexpression of Amphiregulin can lead to increased cancer cell proliferation and it has been implicated in diverse cancers such as breast and colorectal cancer. Additionally the protein plays a role in airway remodeling in asthma contributing to bronchial hyper-responsiveness. In these contexts Amphiregulin's interactions with EGFR are central influencing disease progression and response to treatment.
