RelevanceToxin that seems to act by forming pores in the membrane of the cell. Has a hemolytic and a leucotoxic activity.
HL-60 (Human promyelocytic leukemia cell line) was differentiated into neutrophils by treatments with DMSO. Neutrophils were incubated with serial dilutions of rhIg A and rhIg B at equimolar concentration 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 470/690 nm. Cells only represented by green circles.
EC50 value was found to be 1.10 nM for ab233597 in combination with hIgA.
