Vector Labs Ab03854-10.3 Anti-EpHA3 [IIIA4], Human IgG1, Fc Silent™, kappa (100 μg) Centrifuge Bundle Savings at Sycamore Life Sciences

Description

Product Class: Purified
Clone ID: IIIA4
Heavy Chain Modification: Fc Silent™
Synonyms: Ephrin type-A receptor 3; EPH-like kinase 4; EK4; hEK4; HEK; Human embryo kinase; Tyrosine-protein kinase TYRO4; Tyrosine-protein kinase receptor ETK1; Eph-like tyrosine kinase 1; III.A4
Amount: 100 μg
Application Codes Clone: ELISA ; FC; IP; in vivo; WB; SPR; therapeutic; IF
Shipping Temperature: Wet Ice
Buffer Composition: PBS with 0.02% Proclin 300.
Original Format: IgG1
Storage Temperature: Store at 4⁰C for up to 3 months. For longer storage, aliquot and store at -20⁰C.
Chimeric Use Statement: This chimeric human antibody was made using the variable domain sequences of the original Mouse IgG1 format, for improved compatibility with existing reagents, assays and techniques.
Specificity Statement: The antibody binds to the native EphA3 globular ephrin-binding domain. The antibody targets a site closely adjacent to the heterotetramerization site on the N-terminal of EPHA3's extracellular domain adjacent to the ligand-binding site and has a high affinity for EPHA3.
Application Notes: This antibody was used for detection of hek expressed on LK63 cells by flow cytometry. Hek antigen was immunoprecipitated using the antibody from 125I-labeled LK63 cell lysates (Boyd et al., 1992; PMID: 1737782). The specificity of the chimeric version of the antibody was confirmed by ELISA analysis (US8664365). In a LK63 xenograft model, administration of the antibody inhibited the tumor growth, decreasing the spreading from the bone marrow to the spleen and other organs and increases the latency of the disease. Similar effects were observed in LK63 EPHA3 knock down xenografts. Further, antibody treatment of a xenograft model using EPHA3-transfected Reh, showed reduction in the bone marrow engraftment and increases the latency of the disease (Charmsaz et al., 2016; PMID: 27922598). The antibody bound to the native EphA3 globular ephrin-binding domain with subnanomolar affinity (KD ∼ 0.5 nM) (Smith et al.; 2004; PMID: 14660665). The antibody specifically stained EphA3 in 95% of human tumor tissues from a broad range of cancer types (Vail et al. 2014; PMID: 25125683). The humanized version of the antibody (KB004), was tested in a multi-center Phase 1/2 trial, in patients with EphA3-positive hematologic neoplasms, including Chronic Myelogenous Leukemia, Acute Myeloid Leukemia, Acute lymphoblastic leukemia, Myelodysplastic Syndrome.
