ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Clone 3D13 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects Tyrosine-protein kinase receptor Axl (UFO). It targets an epitope within 23 amino acids from the C-terminal, cytoplasmic domain.

KLH-conjugated linear peptide corresponding to 23 amino acids from the C-terminal, cytoplasmic domain of human Tyrosine-protein kinase receptor Axl (UFO).

Tyrosine-protein kinase receptor UFO (UniProt: P30530; also known as EC:2.7.10.1, AXL oncogene) is encoded by the AXL (also known as UFO) gene (Gene ID: 558) in human. AXL is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-25), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 26-451), a transmembrane domain (aa 452-472), and a cytoplasmic domain (aa 473-894). It serves as receptor tyrosine kinase that transduces signals from the extracellular matrix into the cytoplasm by binding to its ligand the growth arrest specific protein 6 (GAS6) via amino acids 26-92. Ligand binding at the cell surface induces dimerization and autophosphorylation of AXL that activates its kinase activity. Its protein kinase domain is localized in amino acids 536-807. Following its activation, AXL binds and induces tyrosine phosphorylation of PI3-kinase subunits PIK3R1, PIK3R2 and PIK3R3. Other known downstream substrate candidates for AXL are CBL, NCK2, SOCS1 and TNS2. Recruitment of GRB2 and PI3-kinase regulatory subunits by AXL also leads to the downstream activation of the Akt. AXL regulates several physiological processes including cell survival, cell proliferation, migration, and differentiation. The AXL/GAS6 signaling is associated with tumor growth, metastasis, invasion, epithelial-mesenchymal transition, angiogenesis, and drug resistance. Higher expression of AXL is reported in metastatic colon and breast cancer; however, its expression in normal colon tissue is weak. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
