Vector Copy Number Determination

Why is vector copy number determination important?

VCN refers to the number of vector copies integrated into the DNA of a host cell. It’s a crucial parameter in gene therapy and cell engineering, such as CAR-T therapy where viral vectors are used to introduce new genetic material. VCN is important for monitoring transgene expression, optimizing viral dose, and ensuring consistent therapeutic outcomes. However, a high VCN can also increase the risk of insertional mutagenesis and oncogenesis, making it a critical safety parameter.

New Product

GT-Digital Vector Copy Number: WPRE Assay Kit v1.0 for the QIAGEN QIAcuity® Digital PCR System

Detect Woodchuck Hepatitis Virus Post-transcriptional Regulatory Element (WPRE), a common genetic element included in viral vectors to enhance gene expression. Widely used in lentiviral, adeno-associated, and retroviral vectors for delivering therapeutic genes into target cells.
