Bioassay development: Optimizing Effec<strong>to</strong>r:Target<br />

(E:T) ratio<br />

An example: Evaluation <strong>of</strong> different E:T ratios for assay optimization using frozen,<br />

thaw-and-use engineered Jurkat Effec<strong>to</strong>r cells (FcgRIIIA (V158) / NFAT-RE-luc2) with<br />

fresh-from-culture target cells (WIL2-S, CD20+).<br />

• Fixed Effec<strong>to</strong>r cell number<br />

• Varied Target cell number<br />

and E:T ratios<br />

• 6hr induction<br />

• Bio-Glo <strong>Assay</strong> Reagent<br />

Confidential and Proprietary. Not for Further Disclosure.<br />

Higher target cell numbers generate greater fold induction<br />
