OFPSpark Tag Information

OFPSpark is a red (orange) fluorescent protein (excitation/emission maxima are 549 and 566 nm, respectively) derived from DsRed. Possessing high photostability and pH stability, OFPSpark is more than twice brighter than mOrange2. Fast OFPSpark maturation makes it clearly detectable in mammalian cells as early as within 8 hrs after transfection. OFPSpark can be expressed and detected in a wide range of organisms. Mammalian cells transiently transfected with OFPSpark expression vectors produce bright fluorescence in 8 hrs after transfection. No cytotoxic effects or visible protein aggregation are observed. For its monomer structure, OFPSpark performs well in some fusions and protein labeling applications.

Background Information

The B-lymphocyte activation antigen B7-1 (referred to as B7), also known as CD80, is a member of cell surface immunoglobulin superfamily and is expressed on the surface of antigen-presenting cells including activated B cells, macrophages and dendritic cells. As costimulatory ligands, B7-1 which exists predominantly as dimer and the related protein B7-2, interact with the costimulatory receptors CD28 and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) expressed on T cells, and thus constitute one of the dominant pathways that regulate T cell activation and tolerance, cytokine production, and the generation of CTL. The B7/CD28/CTLA4 pathway has the ability to both positively and negatively regulate immune responses. CD80 is thus regarded as promising therapeutic targets for autoimmune diseases and various carcinomas.
