MtoZ Biolabs' HPV18 E6/E7 Residual DNA Fragment Detection Kit (PCR-Fluorescent Probe Method) is specifically designed for the quantitative analysis of HPV18 E6/E7 residual DNA fragment distribution derived from HeLa cells, providing effective support for biopharmaceutical quality control.
Product Overview
The detection of residual HPV18 E6/E7 DNA fragment size distribution in biopharmaceutical samples involves several technical challenges:
1. High Fragmentation
Host cell DNA often breaks into small fragments during biopharmaceutical processes, and traditional detection methods may miss these fragments, leading to inaccurate residual DNA levels.
2. Matrix Effects and PCR Inhibition
Samples like recombinant proteins, antibodies, and vaccines contain proteins, salts, and buffers that can inhibit PCR enzymes, causing false negatives or inaccurate quantification.
3. Sensitivity for Trace DNA
After purification, residual DNA is often very low (pg or fg level), requiring highly sensitive detection with a good signal-to-noise ratio.
4. Fragment Distribution Risk
Longer DNA fragments (>200bp) pose higher tumorigenic or infection risks. Regulatory agencies focus on fragment size distribution, not just total DNA, making detection challenging.
5. Species Similarity Interference
HPV18 DNA shares similarities with other species like the human genome. Lack of specificity in detection targets can lead to cross-reactivity, affecting accuracy and specificity.
Advantages
