Product details:
Abcam's Axl Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an
in vitro
enzyme-linked immunosorbent assay for the quantitative measurement of Human Axl in serum, plasma, and cell culture supernatants.
This assay employs an antibody specific for Human Axl coated on a 96-well plate. Standards and samples are pipetted into the wells and Axl present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Axl 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 Axl bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Optimisation may be required with urine samples.

The Axl protein also known as AXL receptor tyrosine kinase plays a significant role in cell signaling. It has a molecular weight of approximately 98 kDa. Axl is a transmembrane receptor that is expressed in a variety of tissues including the immune system reproductive organs and the central nervous system. It is mainly recognized for transmitting signals from the extracellular matrix into the cytoplasm by binding with its ligand Gas6.
Biological function summary
Axl is important in mediating cell survival proliferation and migration. It functions as part of the TAM family of receptors which also includes Tyro3 and Mer. Axl often forms complexes with these receptors to facilitate efficient signaling. This interaction triggers phosphorylation events that activate downstream signaling proteins reinforcing its influence in cellular functions.
Pathways
Axl is deeply involved in the PI3K-Akt and MAPK signaling pathways which are central to cellular growth and survival. In these pathways Axl interacts closely with proteins like PI3K and Akt to regulate processes such as apoptosis and metabolism. Its interaction with these pathways places Axl as an important modulator of intracellular signaling cascades.
Axl has been implicated in cancer progression and immune response dysregulation. In many cancer types Axl overexpression links to tumor invasion metastasis and resistance to therapy. Moreover Axl’s role in autoimmune diseases becomes evident through its association with the Gas6 protein. Exploring these connections furthers understanding of how Axl's aberrant activity influences health and disease.
