Service Process
Our plasmid DNA preparation service follows a systematic process to ensure accurate and reliable results. Here are the key steps involved:
- Consultation: We begin by understanding your research goals and requirements to customize the plasmid DNA preparation process accordingly. During this phase, we discuss the specific details of your project, including the plasmid of interest, starting materials, and any unique requirements you may have.
- Sample Collection: You provide the bacterial culture containing the plasmid of interest, or if needed, we can assist you in acquiring the necessary starting materials. Our team ensures the proper handling and transportation of the samples to maintain their integrity.
- DNA Extraction: Using optimized methods, we isolate the plasmid DNA from the bacterial cells. Our extraction techniques ensure high purity and yield, resulting in DNA samples of exceptional quality. We take great care to minimize the presence of contaminants and impurities.
- Purification: The extracted DNA undergoes purification to remove contaminants, enzymes, and other impurities. We utilize advanced purification techniques to achieve high levels of purity, ensuring that your plasmid DNA is free from any unwanted substances that may affect downstream applications.
- Quality Control: Quality control is a crucial step in our plasmid DNA preparation process. We perform rigorous quality control checks to verify the quantity, purity, and integrity of the plasmid DNA. Our meticulous testing procedures ensure that you receive reliable and accurate results.
- Delivery: Once the plasmid DNA is purified and passes our quality control checks, we deliver it to you along with comprehensive documentation detailing its characteristics and concentration. We take great care in packaging and shipping the DNA samples to ensure their stability during transportation.

Case Studies
The NTC7382 promoter is shown in Fig. 2. The NTC7382 chimeric promoter is composed of the novel combination of: (1) CMV promoter and start of exon 1; (2) the HTLV-I R-U5 sequence which contains the 5 splice acceptor site; (3) a synthetic 3 acceptor site based on the rabbit globin intron; (4) exon 2 splicing enhancer comprised of SR protein binding site (three copies of GAAGAAGAC) to improve RNA export [16]; prior to (5) exon 2 kozak sequence upstream of the start codon for the gene of interest. Incorporation of the HTLV-1 R-U5 region downstream of the CMV promoter has been demonstrated to improve expression and cellular immune responses to HIV DNA vaccines in mice and nonhuman primates and improve humoral responses to an influenza pDNAVACCUltra based DNA vaccine in mice (compared to CMV promoter based vectors; J. Williams, unpublished observations). Expression levels (of EGFP) from plasmids incorporating the NTC7382 promoter, after transfection of HEK293, are dramatically increased versus CMV based promoter plasmids.
