Biomiga Mouse Anti-Human EphB4 Monoclonal Antibody (Clone #AB107) - AB107-1000

Description : Mouse Anti-Human EphB4 Monoclonal Antibody (Clone #AB107)
Catalog#: Quantity Lot#
AB107-200 200 μg 0706
AB107-1000 1000 μg 0706
Source: Hybridoma cell line was selected from a mouse myeloma fused with B cells obtained from a mouse immunized with purified recombinant human EphB4 extracellular domain. IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.
Formulation: Lyophilized powder lyophilized from phosphate-buffered saline (PBS)
Preservative: None.
Purity: >97% on 15% SDS-PAGE.
Sterility: 0.2 μm membrane-filtered and packaged aseptically.
QC Tests: SDS-PAGE, Immunoprecipitation, direct ELISA,
Reconstitution and Use:
Reconstitute the contents of the vial using sterile phosphate-buffered saline (PBS) to a concentration no less than 100 μg/ml and aliquot for future use. (If the initial rehydration is too dilute, activity may be lost due to the non-specific adsorption to the container). The solution can then be further diluted to a working stock solution.
Storage and Stability:
Upon receiving, store the product at -20°C. After reconstitution, store the working aliquots at 2-8°C for no more than 3 months. For extended storage, aliquot the rehydrated solution (100 μg/ml) and freeze at -70°C or -20°C. Avoid repeated freezing and thawing. More dilute solutions stored at -20°C will lose activity faster.
About EphB4:
EphB4, also known as Htk, Myk1, Tyro11 and Mdk2, is a receptor tyrosine kinase that binds the ligand Ephrin B2, but not other Ephrin ligands. It has been shown to be involved in the regulation of endothelial cells, carcinomas and some hematopoietic cells. It plays important roles during embryonic development including pattern formation, cell aggregation and migration, segmentation, neural development, angiogenesis, and vascular network assembly. It is essential for vascular remodeling, maturation and directed growth. Its expression is restricted to venous endothelial cells.
Specificity:
This antibody was selected for its ability to detect rhEphB4 in direct ELISAs, Western blot, and immunoprecipitation. In these formats, this antibody showed no cross-reactivity with other human EphB receptors, but some activity with mouse EphB4. Its binding epitope is located in the second Fibronectin III domain of the human EphB4. This mouse monoclonal antibody is identified as IgG3.
Applications:
Immunoprecipitation - This antibody can be used at ~ 1 μg/ml to immunoprecipitate human EphB4.
Direct ELISA - This antibody can be used at 1μg/mL with the appropriate secondary antibodies to detect human EphB4 directly coated on an ELISA plate. The detection limit for rhEphB4 is less than 2 ng/well.
Western blot - This antibody can be used at less than 1 μg/ml with the appropriate secondary antibodies to detect human EphB4. However, it is recommended to use mAb105 for the best results of Western blot.
Optimal dilutions should be determined by individuals for each application.
