Bio-Activity
Measured by a cell proliferation assay using human N1186 T cells. The ED50 for this effect is typically 10ng/mL, corresponding to a specific activity of 1x 105 units/mg
Endotoxin
Less than 0.01 EU/µg protein (determined by LAL method).
Presentation
Lyophilized from a sterile solution in PBS.
Reconstitution
10µg size: Reconstitute with 100 µl sterile H2O. 50µg size: Resonstitute with 100 µl sterile H2O. Add 1X PBS to the desired concentration. PBS containing at least 0.1% BSA should be used for further dilutions.
