Creative Biolabs has extensive experience in CART structure design and optimization. The following are some anti-EphA2 CAR related products, if you have any needs, please feel free to contact us.
Erythropoietin-producing Hepatocellular receptor tyrosine kinase class A2 (EphA2) is a 130-kDa transmembrane glycoprotein expressed on a variety of tumor tissues. EphA2 interacts with ephrin A-family ligands and mediates several important signaling pathways, which play key roles in regulating various cellular processes of embryonic development, and tumorigenesis. Based on these properties of EphA2, many studies have targeted EphA2 as one of the promising targets for antibody and CAR-T cell development for cancer therapy.

Anti-EphA2 CAR-T Expression Test
Creative Biolabs offers a complete series of protein products to detect the expression of anti-CD44v6 CART cells. These protein and cell products have been widely used for the expression test of anti-CD44v6 CAR-T cells.
Meanwhile, we offer several robust and reliable approaches for CAR expression testing, including qPCR, WB, and flow cytometry methods.

Anti-EphA2 CAR-T Cytokine Release Test
Cytokine release testing is commonly used to assess the performance of CART cells during co-interaction with tumor target cells. Creative Biolabs is committed to providing global customers with comprehensive cytokine release testing services through sensitive methods, such as ELISA, ELISPOT, multiplex cytokine arrays, and intracellularly FACS staining.
