Your current CGT workflow is stitching together incomplete answers.

If you’re troubleshooting titer-to-potency discrepancies, struggling to characterize impurity integrity, or trying to build a defensible genome integrity story for your IND filing, you already know the problem.

Countable PCR delivers single-molecule resolution for genome integrity assessment — precisely distinguish full-length from partial genomes with the reproducibility your release workflows demand. Measure multiple CQAs simultaneously and establish robust batch comparability, all from one assay.  

Be ahead of the characterization curve. 

With Countable PCR:

True single-molecule counting

Delivers clean, highly precise signal and absolute quantification for highly reproducible results

Combine multiple CQAs in one

Combine multiple CGT critical quality attributes to simplify workflows and reduce cost - such as titer, genome integrity, plasmid-derived impurities or residual host DNA

GMP-friendly

Designed for regulated environments with software built for auditability and compliance

Accelerate assay deployment

Leverage ready-to-use Pre-designed Assays for CGT workflows or use Assay Services for fast generation of proof-of-concept data

White Paper: Cell & Gene Therapy

Analytical characterization is one of the biggest bottlenecks in CGT development. This whitepaper cuts through the complexity, comparing the platforms your team is already using—and showing where single-molecule counting changes the equation.
