Unlock the full potential of your chimeric antigen receptor (CAR) research with our next-generation detection reagent—engineered for unmatched brightness, ease of use and reproducibility.
One-Step Simplicity, No Compromise
Eliminate complex staining protocols. The BD® CAR Detection Reagent is a single-step, ready-to-use solution that streamlines your workflow without sacrificing brightness. Whether you're running a few samples or scaling up, our reagent integrates seamlessly into your flow cytometry assays.
Unparalleled Performance
When it comes to detecting CAR-T cells—especially those with low expression—small differences in performance make a big impact on results. The BD® CAR Detection Reagent consistently delivers exceptional performance across key metrics that matter most to researchers.
Superior Sensitivity
The BD® CAR Detection Reagent reliably detects rare CAR+ cells at frequencies as low as 0.1%, making it ideal for persistence studies and minimal residual disease models. In spiking experiments, our PE-conjugated reagent accurately identified CAR+ cells across a 2-fold dilution series, maintaining linearity and precision even at the lowest concentrations.
Rare Cell Detection. (Jurkat-CAR clone isolated from BCMA (scFv)CAR lentivirus-infected cells was spiked into PBMC from a healthy donor in the Associate Sample Collection Program (ASCP) at approximately 4% and 9 additional descending 2-fold dilutions. Jurkat-CAR-spiked PBMC were stained with PE conjugated BD BCMA CAR Detection Reagent at 0.1 μg/test for 30 min at RT, following by flow cytometric analysis.

Brighter Signal, Better Resolution
Compared to currently available reagent options, our reagents demonstrated:
Higher stain index across all fluorochromes (PE, AF488, AF647, BV421)
Clearer separation of CAR+ and CAR– populations
Better resolution of low-affinity CAR constructs
In head-to-head comparisons, BD reagents consistently outperformed others in both signal intensity and background suppression, ensuring confidence in results.

Compatible with Lysis and Permeabilization Buffers
The BD® CAR Detection Reagents are validated for use with:
Whole blood lysis buffers (Pharm Lyse™, BD FACS™ Lysing Solution)
Intracellular staining protocols (Perm I, Transcription Factor Buffer)
Multi-color panels with minimal spectral spillover
This broad compatibility ensures seamless integration into your existing flow cytometry workflows—without compromising performance.
