Opis

General description

Ephrin type-A receptor 2 (UniProt: P29317; also known as EC: 2.7.10.1, Epithelial cell kinase, Tyrosine-protein kinase receptor ECK) is encoded by the EPHA2 (also known as ECK) gene (Gene ID: 1969) in human. Ephrin type-A receptor 2 (EphA2) is a homodimeric single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-23), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 24-537), a short transmembrane domain (aa 538-558), and a cytoplasmic domain (aa 559-976). It is expressed in brain and glioma tissue and in glioma cell lines. It is also highly expressed in tissues that contain a high proportion of epithelial cells. Its levels are up-regulated by UV irradiation via a TP53-independent, MAPK-dependent mechanism. EphA2 serves as a receptor tyrosine kinase that binds promiscuously membrane-bound ephrin-A family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. It is involved in the regulation of migration, integrin-mediated adhesion, and in proliferation and differentiation of cells. EphA2 is phosphorylated on tyrosine residues upon binding and activation by EFNA1. Phosphorylation on tyrosine 588 and 594 is reported to be essential for binding VAV2 and VAV3 while phosphorylation on Tyr 735 and Tyr 930 are required for binding PI3-kinase p85 subunit. Overexpression of EphA2 is reported in murine models of skin tumors. Inflammatory cytokines are reported to promote RSK-dependent phosphorylation of EphA2 at serine 897 and this RSK-EphA2 axis might contribute to cell motility and promote tumor malignant progression. Two isoforms of Ephrin type-A receptor 2 have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions

Clone 2C3 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects Ephrin type-A receptor 2 (EphA2). It targets an epitope within 15 amino acids from the C-terminal region.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 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.

Preparation Note

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
