The General Introduction of Plasmid DNA Preparation

Plasmid DNA preparation is a process of separating and purifying circular double-stranded DNA molecules (i.e., plasmids) from bacteria (usually Escherichia coli) that contain plasmids. As small DNA fragments independent of chromosomal DNA and capable of autonomous replication in host cells, plasmids often carry genes such as antibiotic resistance genes and fluorescent protein genes, which endow host cells with specific biological characteristics. It is extremely useful in molecular biology research and biotechnology fields. Its main purpose is to provide materials for subsequent experiments such as cloning, sequencing, or serving as a vector for transforming other cells.

Synbio Technologies is dedicated to providing our customers with high-quality and customized plasmid DNA preparation services. We conduct comprehensive quality control of the plasmid products to provide you with aseptic plasmids containing no RNA or genome pollution. All plasmids we manufacture are free of animal-derived materials and can contain low levels of endotoxin (< 100 EU/mg, <30 EU/mg, <5 EU/mg, on request). We provide both research grade and transfection grade plasmids according to our customers needs. Order your plasmid DNA now and experience something brand new right away!

FAQs

What should I do if the plasmid copy number is low?

You can increase the volume of bacterial solution extracted and reduce the volume during elution, or replace it with a high-copy-number vector with the same function.

What are the downstream applications of plasmid DNA?

Our services cater to a wide range of applications, including gene function research, protein production, gene therapy, vaccine development, drug screening, and more.

Can you provide transfection level plasmid DNA?

We provide high-quality plasmid DNA for various applications, including transfection, and our plasmid DNA preparation services can be customized to meet your specific needs. We offer both research-grade and transfection-grade plasmid DNA. Whether you need plasmid DNA for gene delivery, cloning, or gene expression studies, we have reliable plasmid DNA preparation solutions to ensure the best possible results.
