In the field of biotechnology and biomedical research, maintaining the genetic stability and transgene integrity of engineered cell lines is vital. Such attributes influence product consistency, safety, and functionality. Over time, cultured cells may undergo chromosomal rearrangements, copy number alterations, or transcriptional changes, which can significantly challenge the preservation of original cell line characteristics.
At Creative Bioarray, we offer advanced Cell Line Characterization Services aimed at assessing and monitoring the genetic integrity of engineered genomes. Through a blend of cytogenetic, molecular, and sequencing-based techniques, our services provide a multi-level characterization of cell lines, which is essential for downstream translational research.
Featured Characterization Services
Our comprehensive services include:
- Stable Cell Line Genetic Stability Testing: This service helps in assessing chromosomal integrity and transgene stability over time, ensuring consistency across various passages and production timelines.
- Genetic Stability Testing (Locus Amplification + ddPCR): Combining fluorescence in situ hybridization (FISH) with droplet digital PCR (ddPCR), we detect copy number variations and monitor transgene amplification or loss.
- Transgene Mapping (FISH): This method enables precise localization of transgene integration sites within host genomes, providing visual confirmation of chromosomal integration.
- Transgene Mapping (Locus Amplification & Sequencing): By using a powerful combination of PCR-based locus amplification and next-generation sequencing (NGS), we identify exact integration sites and associated genomic sequences.
- Clonality Analysis Service (FISH): A critical requirement for regulatory submissions, this service verifies monoclonality in engineered cell lines through FISH-based single-cell analysis.
Key Analytical Capabilities
Our services are characterized by several key analytical capabilities that enhance the reliability and accuracy of findings:
- High-resolution transgene mapping that identifies integration sites with precision.
- Copy number quantification for accurate measurement of transgene dosage.
- Long-term genetic stability assessment that monitors genomic integrity over multiple passages.
- Splice variant detection to confirm appropriate mRNA processing and identify aberrant splicing.
- Regulatory-compliant clonality proof, providing definitive evidence necessary for FDA/EMA submissions.
