    OFP (OFPSpark) / RFP Tag Info

    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.

    研究背景

    LAG3, also known as CD223 and Lymphocyte activation gene 3, belongs to immunoglobulin (Ig) superfamily. LAG3 contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. It is selectively expressed in activated T and NK cells. LAG3 has a negative regulatory function in T cells. It also acts as as a new marker of T cell induced B cell activation. As a soluble molecule, LAG3 activates antigen-presenting cells through MHC class II signalling, leading to increased antigen-specific T-cell responses in vivo.
