Copy number variation analysis measures the average copy number of a plasmid or integrated expression construct in a cell bank. The FDA requires manufacturers to confirm that the copy number of expressing cell banks whether the cell bank is integrated (the transgene is integrated into the host cell genome), or the cell bank is non-integrated (the expression construct is on an extrachromosomal DNA, typically a plasmid). Avance Biosciences™, Inc. provides all necessary expertise for copy number projects from assay design to consultation regarding the use of a host gene normalizer.

DNA will be extracted from test article and host control cells followed by spectrophotometry quantification and gel electrophoresis analysis. If needed, target-specific and genomic qPCR assays will be developed and qualified. Standard curves will be prepared for both target-specific and genomic assays, respectively. For each test article, six dilutions will be analyzed in duplicate along with Positive Control, Negative Control, and No Template Control using the ABI 7900 HT Fast Real-Time PCR System. Copy number of the target gene per cell will be reported. Custom assays may be developed and validated per ICH guidelines.
