Product Feature: CoraFluor Probes for TR-FRET
CoraFluor™ 1, amine reactive (Catalog:7920) and CoraFluor™ 2, amine reactive (Catalog # 7950) are terbium-based probes that have been developed for use as TR-FRET donors. They emit wavelengths compatible with commonly used fluorescent acceptor dyes such as BODIPY® (or BDY) and Janelia Fluor® dyes, FITC (Catalog # 5440), TMR and Cyanine 5 (Catalog # 5436). CoraFluor™ fluorescence is brighter and more stable in biological media than existing TR-FRET donors, leading to enhanced sensitivity and improved data generation. CoraFluor™ 1 exhibits excitation upon exposure to a 337 nm UV laser.Applications for CTLA-4 Antibody (anti-CTLA4) [CoraFluor™ 1]

Background: CTLA-4
Similar to programmed cell death protein 1 (PD-1), CTLA-4 is an inhibitory immune checkpoint protein (3,5). Checkpoint blockade immunotherapy using drugs or antibodies to target CTLA-4 is one of the main approaches for cancer treatment (5). A number of drugs targeting CTLA-4, or a combination of CTLA-4/PD-1, have been approved for treatment of various cancers like melanoma, renal cell carcinoma, and colorectal cancer (5). While blocking CTLA-4 in the tumor microenvironment is a promising cancer therapeutic, the absence of CTLA-4 under normal conditions can have deleterious effects. Studies have found that patients with CTLA-4 deficiency or mutations have clinical features associated with autoimmunity and immune dysregulation (4). Treatment options for CTLA-4 deficiency includes immunoglobulin-replacement therapy, corticosteroids, CTLA-4-immunoglobulin (Ig) fusion protein, and, in life-threatening cases, hematopoietic stem cell transplantation (4,6). Additionally, engaging CD80/CD86 with CTLA-4-Ig is a common immunosuppressive treatment for rheumatoid arthritis and kidney transplant recipients (6).
