Product Summary for Human Phospho-Axl DuoSet IC ELISA

This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure tyrosine-phosphorylated human Axl in cell lysates. An immobilized capture antibody specific for Axl binds both phosphorylated and unphosphorylated Axl . After washing away unbound material, an HRP-conjugated detection antibody is used to detect only phosphorylated receptor, utilizing a standard HRP format.

Scientific Data Images for Human Phospho-Axl DuoSet IC ELISA

Figure 1. The Human Phospho-Axl DuoSet IC ELISA is more sensitive than immunoprecipitation (IP)-Western analysis

Human glioblastoma cell line, A172, was treated with conditioned media from the human lung cell line, WI38, for fifteen minutes to induce tyrosine phosphorylation of Axl. Serial dilutions of lysates were analyzed by (A) IP-Western blot and (B) this ELISA . IPs were done using an anti-Axl monoclonal antibody and anti-mouse IgG agarose. Immunoblots were incubated with a biotinylated anti-phosphotyrosine monoclonal antibody (Catalog # BAM1676) to detect phospho-Axl (p-Axl). Bands were visualized with Streptavidin-HRP (Cat # DY998) followed by chemiluminescent detection.

Figure 2. The Human Phospho-AxlDuoSet IC ELISA detects ligand-induced Axl tyrosine phosphorylation

A172 cells were untreated or treated with conditioned media from the human lung cell line, WI38, for fifteen minutes. ELISA and IP-Western blot (inset) analyses were done using 100 μg and 400 μg of lysate, respectively. IP-Western blots for phospho-Axl (p-Axl) were done as described in Figure 1. Blots were stripped and total Axl was detected using a biotinylated anti-Axl polyclonal antibody (Catalog # BAF154).

Figure 3. The specificity of the Human Phospho-AxlDuoSet IC ELISA is confirmed by receptor competition

A172 cells were treated with conditioned media from the human lung cell line WI38 for fifteen minutes. The indicated amounts of recombinant extracellular domains of human Axl (Catalog # 154-AL), human Dtk (Catalog # 859-DK) or human Trk A (Catalog # 175-TK) were added to 125 μg lysate and analyzed using this ELISA. Competition was observed only with recombinant Axl.

Background: Axl

Axl (Ufo, Ark), Dtk (Sky, Tyro3, Rse, Brt) and Mer (human and mouse orthologs of chicken c-Eyk) constitute the TAM receptor tyrosine kinase subfamily. This RTK subfamily is characterized by an extracellular domain that consists of two Ig-like motifs and two fibronectin type III motifs. These receptors bind the vitamin K-dependent protein Growth Arrest Specific Gene 6 (Gas6). Receptor activation leads to cell proliferation, migration, or the prevention of apoptosis. Cellular signaling through this family of RTKs is involved in hematopoiesis, embryonic development, tumorigenesis, and spermatogenesis.
