CAR T cell research solutions

Starting your workflow with a well-defined, enriched T cell population is key to obtain robust, standardized, and reproducible results. Depending on the starting material, PBMCs or blood products, you choose either standard MACS® MicroBeads and Isolation Kits or the innovative StraightFrom® Technology. But independent of the approach, the basis is always the proven and most cited MACS MicroBead Technology. In addition, to enable a seamless transition of your research workflow to the CliniMACS Prodigy® Platform, MACS MicroBeads are available in MACS GMP Quality. 

Separation of T cells from PBMCs

Positive selection enables straightforward isolation of CD4⁺ and CD8⁺ T cells from PBMCs using MACS MicroBeads and MicroBead Kits. 

Separation of human T cells directly from blood products

Increase throughput and productivity with StraightFrom® Technology for T cell isolation directly from whole blood and blood products (buffy coat, LRSC, and Leukopak®) without density gradient centrifugation or RBC lysis.

CAR T cell enrichment from patient blood

The MACSprep™ CD19 CAR MicroBead Kit was developed for fast and convenient CAR T cell isolation from fresh blood samples.

Physiological T cell activation is vital to start the proliferation and expansion process and facilitate an efficient T cell transduction. Optimal T cell expansion relies on the synergistic effect of T Cell TransAct™, TexMACS™ Medium, and MACS Cytokines.  

Transgene expression depends on gene transfer efficiency. However, viral transduction of suspension cells with retroviral vectors is often inefficient and requires the use of transduction enhancers.   
Using the synthetic, non-toxic soluble Vectofusin®-1 with a simple and easy-to-follow protocol enhances the transduction efficiency of viral vectors.  

As the success of CAR T cell therapies has been associated with the phenotype, activation status, and functional profiling of CAR T cells, the reliable and standardized characterization of those parameter is crucial. 
Our CAR T cell analytics portfolio provides all you need for reliable, reproducible, and standardized analysis. Use our high-quality reagents, instruments, and software to streamline your CAR T cell analysis – from basic research and discovery to IPC/QC in clinical manufacturing.

Or watch our three-part webinar series on  Standardizing flow cytometry assays in cell manufacturing to learn about automated tools for CAR T cell analysis.

Phenotypic characterization

Our optimized and validated panels of fluorochrome-conjugated REAfinity™ Recombinant Antibodies and CAR Detection Reagents help to streamline the phenotypic characterization of CAR T cells. For maximum reproducibility and standardization of in-process-control (IPC) and quality control (QC) for your clinical manufacturing process, combine the StainExpress™ Dried Antibody Cocktails with the MACSQuant® Analyzer and the Express Modes. 

Validated panels for CAR T cell flow analysis

Benefit from Miltenyi Biotec Tested Panels (MBTP) including antibody panels, step-by-step protocols, and gating strategies to accelerate your CAR T cell flow analysis.

Reliable detection and enumeration of CAR-expressing T cells

Our ready-to-use biotinylated CAR Detection Reagents have been developed for the detection of T cells that are engineered to express a specific CAR on the cell surface, e.g., CD19 CAR or CD22 CAR. 

Functional CAR T cell analysis 

We offer flow cytometry solutions to improve the quality of potency assay results. They can, for example, be used for high-throughput and automated in vitro potency assays to assess CAR T cells’ antigen-specific killing, T cell phenotype, intracellular cytokine detection, as well as effector cytokine secretion.

Rapid Cytokine Inspector Kits offer the fastest combination of surface marker and intracellular cytokine staining

• High-throughput multiparameter analysis of antigen-specific T cells.
• Rapid identification and enumeration of cytokine-producing activated antigen-specific CD4⁺ and CD8⁺ T cells upon in vitro stimulation with the respective antigen or upon polyclonal restimulation.
• Immunomonitoring of antigen-specific T cells.

Ultra high content imaging allows for CAR T cell target discovery, in-depth tumor infiltration analysis, as well as assessment of preclinical CAR T cell target safety and CAR T cell biodistribution.
