Scientific Data Images for CD57 Antibody (NK1/7565) [CoraFluor™ 1]
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 CD57 Antibody (NK1/7565) [CoraFluor™ 1]

Background: CD57
CD57 expression has become a common pathological marker. CD57+ CD8+ T cell expression is observed in various cancers and is often linked to reduced survival (3). On the other hand, CD57+ NK cell expression is associated with less severe disease and better prognosis in cancer patients (3). CD57 is also associated with immune dysfunction and autoimmune disease (3,4). For example, T cell immunosenescence is characterized by an upregulation of CD57 along with KLRG-1 and a loss of CD27 and CD28 expression (4). Expanded autoreactive T cells are also related to diseases including multiple sclerosis (MS) and rheumatoid arthritis (RA) (3). Conversely, reduced numbers of CD57+ NK cells and NK cell cytotoxicity is observed in various autoimmune diseases such as apoptotic dermatitis and sjogren's syndrome (3).
