Client Needs: Required ultrasensitive monitoring of host DNA clearance during viral vector production.
Challenges: In-house methods lacked the sensitivity to evaluate the true efficiency of critical purification steps.
Solution: We implemented a droplet digital PCR (ddPCR) assay specifically designed for their production cell line. This absolute quantification method provided a complete DNA clearance profile by analyzing intermediates from crude harvest to final product with single-molecule sensitivity, precisely identifying the bottleneck in the purification process.
Outcome: The client optimized their downstream process, significantly improving final product quality consistency.
Client Needs: A manufacturer needed to identify the source of trace peanut DNA residue on a production line.
Challenges: The contaminant was minute and unstable, making precise source identification impossible with conventional tests.
Solution: We employed a combined strategy of real-time PCR and DNA sequencing. Using highly specific primers, we amplified and sequenced DNA from environmental swabs, comparing the fragments to the raw material library. This confirmed not only the allergen's presence but also pinpointed the exact contaminated ingredient batch.
Outcome: The client rapidly identified the contamination source and implemented targeted improvements to their raw material handling.
Client Needs: The client needed to identify the source of an unspecified biological contaminant causing aberrant cell growth.
Challenges: The contamination showed no distinct microscopic features, and standard microbial tests returned negative results.
Solution: We applied metagenomic next-generation sequencing (NGS) to unbiasedly analyze free DNA in the culture supernatant. Through deep sequencing and bioinformatic comparison, we successfully identified the presence of specific viral sequences undetectable by culture methods, defining the contaminant's nucleic acid signature.
Outcome: The client received a definitive identification, providing the critical evidence needed to sanitize the culture system and restore production.
Residual DNA testing refers to the detection of trace amounts of DNA left in samples, commonly used to assess DNA contamination in biopharmaceutical products, environmental samples, or food. Through high-sensitivity techniques like PCR or real-time quantitative PCR (qPCR), we can precisely identify and quantify these DNA residues to ensure the integrity of production processes, product quality, and environmental monitoring.
DNA residues are small fragments of DNA that remain in samples, typically originating from biological organisms or biological products. These residues can result from cell lysis, cross-contamination during production, or external environmental contamination. With precise DNA analysis methods, these residues can be detected, their sources identified, and their concentration quantified to assess potential impacts on products or environments.
The four main types of DNA analysis are: Qualitative DNA Analysis: Detects the presence of specific DNA or genes. Quantitative DNA Analysis: Measures the exact concentration of DNA, often used to assess contamination levels. DNA Source Tracing: Identifies the origin of DNA, helping trace species or sources. Genomic DNA Analysis: Provides a comprehensive analysis of all DNA within a sample, focusing on structure and function.
DNA residue analysis is critical for ensuring the quality of biopharmaceutical products and food. It helps identify potential contamination sources, prevent cross-contamination, and ensure product consistency and safety. For environmental monitoring, DNA residue testing evaluates the spread of GMOs or harmful substances, helping optimize production processes and improve compliance with safety standards.
DNA residue analysis typically involves sample collection, DNA extraction, and PCR or qPCR testing. First, DNA is extracted from the sample and purified. Then, specific PCR techniques are used to amplify target DNA fragments. By analyzing the quantity and characteristics of the amplification products, the presence and concentration of DNA residues are determined, providing accurate analysis results.
