Fig. 2From: Confirmation of covalently-linked structure and cell-death inducing activity in site-specific chemical conjugates of human Fas ligand extracellular domainCell-death inducing activity of FL-hFasLECD conjugate. a Concentration dependency of FL-hFasLECD. The numerals represent the treatment concentration of FL-hFasLECD and FL-BSA in ng/ml. PBS, negative control buffer used for the dilution of samples; pretreatment condition: −, no IFN-γ; +, 100 IU/ml of IFN-γ. Treatment time 72 h. b, c Concentration dependency of IFN-γ. Colors: blue, PBS alone; green, FL-BSA; orange, FL-hFasLECD. Sample concentration: b 100 ng/ml; c 1000 ng/ml. Treatment time 72 h.
