Exogenous gene copy number detection is used to determine whether there is any abnormal proliferation, loss or recombination of exogenous genes during the production process of gene therapy preparations. The copy number may affect the expression level and performance of the product, and thus the dosage of the product, so monitoring the copy number ensures that the product produced meets the quality standards and safety requirements. In addition, exogenous gene copy number testing can also be used to determine the consistency and stability between production batches, because copy number changes may be associated with adverse events or mutations in the production process, so exogenous gene copy number testing is a reference for the optimization of the production process.
CD Formulation provides comprehensive solutions for quality control of gene therapy formulations, especially in the detection of exogenous genes. We not only have a great deal of experience in exogenous gene identification, but we also have sophisticated and all-inclusive testing platforms that enable us to precisely assess exogenous gene presence and expression.
Exogenous gene testing is essential to ensure the safety and efficacy of gene therapy formulations. It can help to identify and quantify exogenous genetic components in a product and assess latent risk and immunogenicity. In addition, exogenous gene testing can monitor the purity and stability of the product during the manufacturing process to ensure that the quality of the final product meets standards.
To ensure the safety and efficacy of gene therapy formulations, exogenous gene detection is indispensable. By employing advanced detection techniques such as qPCR and dPCR, we can accurately assess the presence of exogenous genes and their expression, and identify potential problems promptly.
Quantitative PCR (qPCR) is a technique used to detect and quantify specific DNA sequences. It is used to quantify the expression level of a target gene by monitoring the amount of amplification product in real-time during PCR amplification using specific primers and probes. qPCR can accurately determine the expression level of an exogenous gene in a therapeutic product. It also evaluates the efficiency of gene introduction by detecting the copy number of the exogenous gene. qPCR can detect a very low amount of the target gene during exogenous gene detection, and can also monitor the results in real-time during each cycle of PCR amplification to obtain rapid quantitative data.
Digital PCR (dPCR) can provide more precise copy number information, which is useful for monitoring the copy number variations of exogenous genes. dPCR can detect a very low abundance of target genes, and can also monitor results in real-time during each cycle of PCR amplification for rapid quantitative data. Since dPCR does not rely on standard curve error, it can identify extremely low target gene abundances and yield more accurate quantitative data, leading to more dependable results.

The article compares traditional transgene copy number detection methods like Southern blot analysis with real-time PCR, highlighting the latter as a faster and more cost-effective alternative. However, real-time PCR results can be inconsistent due to a lack of robust statistical analysis and quality control. The article discusses three experimental designs and four integrated statistical models to improve the accuracy of transgene copy number estimation using real-time PCR. These methods include external calibration curves, internal reference gene comparisons, and fluorescence data analysis without standard curves. The authors emphasize that proper statistical treatment, including confidence intervals, is essential for precise estimation. The proposed statistical approaches can also be applied to other PCR-based quantification assays.
