Genomic and Molecular ServicesDroplet Digital PCR Applications for Cell and Gene Therapy Unrivaled Precision and Accuracy for Quality Manufacturing
Droplet Digital PCR (ddPCR) provides highly precise, absolute quantification of nucleic acid sequences by counting nucleic acid molecules encapsulated in discrete, volumetrically defined water-in-oil droplet partitions. This digital measurement is suitable for the analysis of both, in-process samples and final drug products, due to the inhibitor tolerant nature of Droplet Digital PCR. This insensitivity to formulation matrices enables the implementation of Droplet Digital PCR throughout the entire manufacturing process. Bio-Rad’s ddPCR systems utilize a simple workflow with minimal hands-on time while reducing sample replicates and user-to-user variability.

Droplet Digital PCR Tools for Adeno-Associated Virus and Lentivirus Production in Gene Therapy
Developing effective and reproducible gene therapies requires the use of sensitive and robust testing methods, such as Droplet Digital PCR, to validate the quality of the therapeutic product. Bio-Rad’s portfolio of ddPCR Viral Quantification solutions offers an accurate, precise, and robust method to measure the viral titer in a sample. Customers may also use some of these solutions to perform quality checks on incoming plasmids and conduct biodistribution studies.

ddPCR Assays for AAV Viral Titer Quantification
MOgene Droplet Digital PCR (ddPCR) Assays for AAV viral titer utilize the precision and sensitivity of ddPCR technology to deliver an absolute count of AAV vector genome copies in your sample. These assays can be ordered through the Cell and Gene Therapy Design Engine and come in two varieties:
– Custom ddPCR Cell and Gene Therapy Assays generated for target gene of interest
– Ready-to-order ddPCR Expert Design Assays for common viral vector and
plasmid elements
Droplet Digital PCR Tools for CAR-T Development and Monitoring in Cell Therapy
Development, validation, and implementation of robust and accurate methods are vital to test the safety and efficacy of gene-modified cell therapies, such as Chimeric Antigen Receptor T (CAR-T) cells. Droplet Digital PCR offers absolute quantification of transgene copy number in a sample. This method can be used to effectively quantify CAR copy numbers in transfected or transduced T cells or count the number of cells that contain the transgene of interest. This is especially important for transgenes that cannot be detected by antibodies. The ddPCR Whole Cell DNA Workflow is a reproducible and easy way to measure the percentage of edited cells with minimal input cells, which can be applied at multiple steps during the cell therapy manufacturing process.

Unrivaled Precision and Accuracy for Quality Manufacturing
droplet digital PCR
MOgene uses QX200 AutoDG ddPCR system (Bio-Rad Labs Inc.) which generates water-oil emulsion droplets that partitions the single PCR reaction into 20,000 droplets and the presence or absence of the fluorescent PCR product in each of these droplets is counted to evaluate the target concentration. This ability to evaluate the DNA abundance in tens of thousands of individual reactions increases the precision as well as the sensitivity of these assays. MOgene offers both custom and commercially available assays for a wide variety of applications such as gene expression and genetic variation analysis. We manage all aspects of the project from assay design and nucleic acid isolation, to data analysis.
