► Single Donor-Derived KILR CD16 Effector Cells for ADCC and T Cell Redirection Applications

Learn how KILR® CD16 effector cells ensure assay reproducibility with higher signal to background ratios, without worrying about donor variability.

PBMC effector cells have inherent donor variability, reducing their consistency and reproducibility in lot release assays. Antibody-Dependent Cell Cytotoxicity (ADCC) assays that measure cell death often have low signal to background ratios and suffer from this donor variability of the PBMCs. 28 min.
