Data Examples

Immunohistochemistry Phospho-Axl (Y779) antibody in Human Stomach Cancer Tissue by Immunohistochemistry (IHC-P). View Larger

Phospho-Axl (Y779) in Human Stomach Cancer Tissue. Axl phosphorylated at site Y779 was detected in immersion fixed paraffin-embedded sections of human stomach cancer tissue using Human Phospho-Axl (Y779) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2228) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rabbit HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS005) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Detection of Human Phospho-Axl (Y779) by Western Blot. Western blot shows lysates of A172 human glioblastoma cell line untreated (-) or treated (+) with WI38 human lung cell line conditioned media (WI38 CM) for 15 minutes. PVDF membrane was probed with 1 µg/mL of Human Phospho-Axl (Y779) Antigen Affinity-purified Polyclonal Antibody, followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-Axl (Y779) at approximately 140 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Phospho-Axl (Y779) in A172 Human Cell Line. Axl phosphorylated at Y779 (panels B, D) and total Axl (panels A, C) were assessed in immersion fixed A172 human glioblastoma cells incubated with (panels C, D) or without (panels A, B) pervanadate. Phospho-Axl was detected using Rabbit Anti-Human Phospho-Axl (Y779) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2228) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red, panels B, D); Catalog # NL004) and counterstained using DAPI (blue). Total Axl was detected using Goat Anti-Human Axl Antigen Affinity-purified Polyclonal Antibody (Catalog # AF154). Cells were stained using the NorthernLights™ 493-conjugated Anti-Goat IgG Secondary Antibody (green, panels A, C); Catalog # NL003). Specific staining was localized to cytoplasm.

Background: Axl

Axl (Ufo, Ark), Dtk (Sky, Tyro3, Rse, Brt), and Mer (human and mouse homologues of chicken c-Eyk) constitute a subfamily of the receptor tyrosine kinases (1, 2). The extracellular domains of these proteins contain two Ig-like motifs and two fibronectin type III motifs. This characteristic topology is also found in neural cell adhesion molecules and in receptor tyrosine phosphatases. The human Axl cDNA encodes an 887 amino acid (aa) precursor that includes an 18 aa signal sequence, a 426 aa extracellular domain, a 21 aa transmembrane segment, and a 422 aa cytoplasmic domain. The extracellular domains of human and mouse Axl share 81% aa sequence identity. A short alternately spliced form of human Axl is distinguished by a 9 aa deletion in the extracellular juxtamembrane region. These receptors bind the vitamin K‑dependent protein growth arrest specific gene 6 (Gas6) which is structurally related to the anticoagulation factor protein S. Binding of Gas6 induces receptor autophosphorylation and downstream signaling pathways that can lead to cell proliferation, migration, or the prevention of apoptosis (3). This family of tyrosine kinase receptors is involved in hematopoiesis, embryonic development, tumorigenesis, and regulation of testicular functions.
