Cell line characterization is the first step in the development of a cell bank that produces a biopharmaceutical. The characterization of each cell line allows the best candidates to be screened for further development. This characterization typically includes some phenotypic and genotypic identity testing.

Sanger Sequencing

Genotypic
Identity Testing

cDNA sequencing data is central to genotypic identity testing. This step confirms the RNA stability of your mammalian or insect cell line.
QPCR

Copy Number
Variation Analysis

Copy number determination by qPCR provides gene dosage and an indication of productivity whether the copy number is plasmid based or an integrated construct.
Southern Blot

Structural Analysis
by Southern Blot

Southern blotting confirms that the correct structure is present in the construct of interest and helps to confirm DNA identity, size, and abundance.
dPCR

Digital PCR Rare
Mutation Analysis

Droplet partitioning allows the dPCR method to effectively increase any rare target abundance; each short area of DNA is amplified including the rare mutations.
Next-Gen Sequencing

Next-Gen
Gene Integration Study

Traditionally, Southern blot analysis is the method of choice to satisfy FDA’s requirements of charactering cell line genetic stability. Avance Biosciences is now offering two NGS approaches to analyze the transgene insertion sites.
Next-Gen Sequencing

Next-Gen Adventitious
Agents Testing

Next generation sequencing is quickly gaining regulatory agencies’ acceptance as a sensitive and un-biased detection method for adventitious agents.
Next-Gen Sequencing

Next-Gen Difficult
Plasmid Sequencing

Next generation sequencing uses short read lengths and high data volumes which allows repeats and high GC regions to be more easily sequenced than with Sanger sequencing.
Next-Gen Sequencing

Next-Gen
Mutation Analysis

We have designed several amplicon sequencing assays to help the client confirm whether mutations exist in their prepared cell lines.  Two-step limited cycle PCR is followed by paired-end next-gen sequencing.
