Synthetic DNA encoding a fusion of an improved IL2 signal sequence (Zhang et al. 2005 & Naito et al. 2013), an octahistidine-tagged-leucine zipper motif, a flexible 17aa linker (Naito et al. 2013) and the death inducing, c-terminal extracellular domain (aa137-208) of CD95L. The cloning strategy omits the proteolytically-susceptible extracellular stalk region (aa102-136), but includes the extracellular self-assembly domain (aa137-183; Orlinick et al. 1997). NTA column purified LZ-CD95L produced in expi393 cells is highly active (IC50 Jurkat E6-1 cells < 50ng/ml). Human CD95L is also active in inducing cell death in murine thymocytes (McLellan et al. 2000). Note, during following transient transfection, rising levels of LZ-CD95L in the culture supernatant induce cell death in HEK293FT and expi293. Users could explore co-transfection of this vector with a c-FLIP-encoding vector, select CD95L resistant HEK293 variants, or use other CD95L-resistant mammalian cell lines to maximise LZ-CD95L yields.
