Functional Studies - Recombinant LukD protein (ab190423)Toxin Functionality: Human promyelocytic leukemia cell line HL60 was differentiated into neutrophils by treatment with DMSO. Neutrophils were incubated with serial dilutions of rLukE and ab190423 alone (Open circles and open squares, respectively) or equimolar concentration of both proteins (Closed circles) for 3 hours at 37°C with 5% CO2 and 95% humidity. Cellular viability was determined by adding XTT and incubation for additional 16 hours. Cells were centrifuged and the OD determined in the supernatants at 470nm. EC50 was found to be 95.1 nM of each toxin subunit.
