Plasmid Characteristic Identification

During GMP plasmid production, enzymatic identification and sequencing identification are important quality control steps to ensure the purity and integrity of plasmid DNA. Any change or mutation in the plasmid sequence can lead to significant problems downstream. Creative Biogene implements a rigorous quality control program during GMP plasmid production, providing highly sensitive and accurate assays that can detect even small changes in plasmid sequence, thus effectively ensuring the safety and efficacy of the final plasmid product for its intended use.

Plasmid Characteristic Identification Methods at Creative Biogene

  • Enzyme digestion identification

Enzyme digestion identification involves the use of restriction endonucleases, which are enzymes that cut DNA at specific sites. These enzymes verify the identity of the plasmid by cutting the plasmid at a site specific to the plasmid. The fragments obtained are then analyzed by gel electrophoresis to confirm the identity of the plasmid.

  • Sequencing Identification

Sequencing identification involves the use of DNA sequencing techniques to determine the exact sequence of a plasmid. This method is particularly useful for detecting mutations or variants in plasmid sequences that may have been introduced during production. DNA sequencing relies on the use of specific primers that bind to plasmid DNA and initiate a sequencing reaction. The resulting sequence is then compared to the expected sequence to verify the identity of the plasmid. Creative Biogene offers reliable Sanger sequencing technology that can be used not only for accurate determination of plasmid sequence authenticity, but also for detection of contaminants or other impurities in plasmid DNA.

The identification methods provided by Creative Biogene are a key component of the quality control process for GMP plasmid production and are critical to ensuring that the final product is safe and effective for its intended use. Please feel free to contact us if you have a need, and our experienced specialists will be happy to assist you.
