StimCytes™ CD19 are precision engineered synthetic cell mimics designed to support CAR‑T potency assessment through targeted CD19 specific activation, cytokine release and biomarker driven assay development. Each kit enables baseline, enhanced and negative activation profiles of CD19 directed CAR‑T cells during antigen engagement.

Unlike cell controls, StimCytes™CD19 provides consistent antigen expression and reproducible activation characteristics that remove the variability associated with donor derived materials. These lyophilized synthetic cells feature selected biomarkers that support stable potency evaluation and streamlined assay optimization across experiments and platforms. The kit includes a high activation mimic with enhancers, a baseline activation mimic and a non activating negative control to establish clear functional benchmarks.

StimCytes™CD19 are intended for research use only and are not suitable for diagnostic or therapeutic procedures. These products are safe to use in any environment, contain no biohazardous material and require no special disposal. (FKA: TruCytes Potency CD19).
