ALX-522-020 SDS-PAGE
SDS-PAGE analysis: Lane 1: MW Marker, Lane 2: 1μg SuperFasL, stained with Imperial stain.
ALX-522-020 Celldeath
Jurkat Cell Death: 50,000 Jurkat cells per well are incubated with the indicated concentration of SuperFasL for 3 hours. Cell death is determined by Cell-titer AQueous one-solution cell proliferation reagent. Formazan product is allowed to develop for 6 hours before the plate is read at 490nm. % Viability is determined in comparison to control well with no SuperFasL.
