Science Behind the System
Quantitative CAR-T Cell Detection and Precise Receptor Density Measurement
SCOPE Technology is an engineered antigen-based detection and calibration platform designed for high-precision CAR surface quantification. It enables accurate measurement of Accessible CAR Molecules (ACM) per cell and establishes reproducible receptor density assessment across laboratories.
The SCOPE detection reagent is built on a precisely engineered antigen-binding architecture combined with site-specific enzymatic biotinylation.
Unlike random chemical labeling approaches, enzymatic labeling ensures a defined fluorochrome-to-binding ratio, enabling predictable signal behavior and improved batch consistency.
This controlled design forms the molecular basis for accurate quantitative receptor density measurement.

In the absence of calibrated reference standards, CAR-T cell detection often relies on subjective gate placement and relative fluorescence interpretation.
This leads to inter-operator variability, limited cross-site comparability, and lack of molecular quantification.
Current workflows classify cells as positive or negative but do not define receptor density in standardized molecular units.

SCOPE Technology integrates engineered reference cell mimics expressing defined and batch-quantified receptor densities. Each reference material is characterized for its precise number of accessible CAR-binding sites per unit, establishing a molecular calibration baseline.
By staining both reference materials and patient-derived CAR-T samples with the same site-specifically labeled detection reagent, a controlled fluorescence-to-receptor relationship is established.
Because each detection reagent molecule carries a defined fluorochrome stoichiometry through enzymatic biotin labeling, fluorescence intensity can be mathematically translated into receptor density.
