Specification

• Source: Baculovirus Sf21 Insect Cells
• Species: Rat
• Form: Lyophilized from a 0.2 µm filtered solution in PBS with BSA as a carrier protein.
• Bio-activity: Measured in a cell proliferation assay using PHA-activated mouse splenocytes. Mattner, F. et al. (1993) Eur. J. Immunol. 23:2202.The ED50 for this effect is typically 0.025 - 0.25 ng/mL.
