  • General notes

    EphA4 (the antigen to this antibody) is also known Sek, Sek1, Cek8, Hek8 and Tyro1 and binds to ephrin-A5, ephrin-A1, ephrin-A3, ephrin-A2, ephrin-B2, ephrin-B3 and ephrin-A4. EphA4 can be detected in B cells, T cells and keratinocytes (ref 1,2). To date, at least 14 members of the Eph receptor family and a family of 8 ligands have been identified. Ligands of Eph family receptors are structurally related membrane-bound proteins that can be subdivided into two major subclasses: ephrin-A and ephrin-B (ref 2). Ligands in the ephrin-A subclass, including the prototype family member ephrin-A1 (B61), are membrane associated through glycosylphosphatidyl-inositol linkages, whereas ephrin-B subclass consists of ligands with transmembrane domains. The a general role of the Eph family is in mediating repulsive cell-cell interaction, as suggested by studies of axonal guidance and neural crest cell migration.

Customer reviews and Q&As


The crossreactivity of this Ab with Ephrin A5 was based on Purification test data, and the estimation was accurate. QC did not test its crossreactivity with mEphrin A5, because mEphrin A5 was not listed as a crossreactant for mEpHA4 Ab. The immunogen for this antibody was affinity purified on a mEphrin A5 column and this may be the cause of the crossreactivity.
