Chimeric Antigen Receptor Modified T-cell Therapy, CAR T-cell therapy, is a type of cancer immunotherapy that has gained world-wide interest in recent years, especially after FDA approval of CAR T-cell therapy for B-cell acute lymphoblastic leukemia and large B-cell non-Hodgkin’s lymphoma. To ensure the safety of the CAR T-cell therapy, regulatory agencies require thorough characterization of the manufactured CAR T-Cells.  In addition, during the clinical trial or patient treatment phase, the level of modified T-cells in patients’ blood must be monitored frequently in a timely manner.

Cell Therapy Testing Services


Copy Number Analysis
for CAR T-cells

Regulatory agencies require CAR-T sponsors to determine the copy number of the inserted genes in manufactured CAR T-cells before releasing for patient treatment.  Avance Biosciences™’ team has more than two decades of experience in designing and validating qPCR copy number assays, and executed hundreds of copy number analysis projects in compliance with CGMP regulations.

Biodistribution Testing

qPCR for Preclinical
Biodistribution Study

In vivo toxicity studies, and sometimes shedding study, are required by regulatory agencies to evaluate the safety of therapeutic cells. Avance Biosciences™ offers GLP compliant qPCR, ddPCR, and NGS amplicon sequencing services to accurately assess the quantity of therapeutic cells in animal blood, CFS, and tissues for biodistribution studies.

Next-Gen Sequencing

Integration Site

Avance Biosciences™ can help our clients to design and execute custom assays to determine gene insertion sites. We use a  combination of NGS, PCR, and Sanger sequencing methods to delineate and validate potential insertion junctions and their locations in host genome.


Replication Competent
Lentivirus (RCL) Assay for CAR T-cells

Lentivirus is commonly used to generate CAR-T cells due to its ability to insert genes into host genome.  It is critical to ensure that there is no replication competent lentivirus (RCL) in the therapeutic cells.  Avance Biosciences™ provides fast turn-around RCL assay services using qPCR and ddPCR methods.


Testing of RNAs in Animal Tissues and Human Blood

Avance Biosciences™ is experienced in supporting our clients for pharmacokinetics study of mRNA or miRNA in animal tissues and in human blood.  Our study directors and lab analysts are proficient in qPCR and ddPCR assay design and validation, for both relative and absolute quantification of RNAs.

All Avance Biosciences™ Services Include

  • Methods validated per ICH GLP/GMP guidelines – also research grade testing available
  • Independent quality unit assuring regulatory compliance
  • Experienced scientists functioning as project managers or study directors
  • Controlled laboratory environment to prevent cross-contamination

Choose Avance Biosciences™ as your trusted partner in CAR T-Cell Therapy Testing, ensuring the safety and efficacy of modified T-cells and compliance with evolving regulatory standards.
