How SCOPE Reagents Are Engineered

The SCOPE Technology Platform

Engineered antigen-based detection reagents for precise, low-background, and reproducible CAR-T flow cytometry.

BlueRay SCOPE reagents are designed from the molecular level upward — combining structure-guided antigen engineering, Fc-background reduction, site-specific labeling, and validation on real CAR-T cells to support reproducible CAR-positive cell detection and optional receptor-density analysis.

SCOPE detection reagent molecular structure

F:P Ratio

Consistent across lots

Step 01

Optimized Antigen Domain

Structure-guided antigen-domain design preserves CAR-recognition surfaces while improving accessibility, stability, and flow cytometry performance.

Step 02

Engineered Spacer Architecture

Spacer and hinge architecture are optimized to support efficient CAR engagement across different CAR constructs, hinge lengths, and receptor presentations.

Step 03

Reconfigured Fc Region

Fc-region engineering is designed to reduce nonspecific Fc-mediated background and improve separation between CAR-positive and CAR-negative populations.

Step 04

Site-Specific Fluorochrome Conjugation

Site-specific enzymatic labeling supports a defined conjugation architecture, controlled fluorochrome configuration, and batch-to-batch consistency.

Step 05

Defined F:P Ratio

Controlled fluorochrome-to-protein configuration helps reduce lot-dependent variation and supports comparable staining intensity across production batches.

Validated on Real CAR-T Cell Samples

SCOPE reagents are evaluated on real CAR-T cell samples across different CAR constructs, receptor densities, hinge designs, and spacer architectures. This practical validation helps ensure that reagent performance reflects real flow cytometry use cases.
