Plasmid Preparation




Epoch Life Science's high-quality plasmid preparation purification service is designed to meet all of your molecular biology research needs. With years of experience in plasmid preparation and purification, our team of experts is committed to providing you with reliable and efficient plasmid preparation solutions. You can expect fast turnaround times, competitive pricing, and exceptional customer service.

Our plasmid preparation purification service utilizes the latest technologies and equipment to produce high-quality plasmid DNA with ultra low  endotoxin level, minimal gDNA, RNA and protein contamination, high percentage of supercoiled fraction.

Endotoxins can be toxic to mammalian cells and can lead to reduced cell viability and protein expression. Using our endotoxin-free plasmids can minimize the cellular toxicity, leading to improved cell viability and protein expression, producing more consistent and reproducible results.

Our plasmid preparation service is customizable to meet your specific research needs.

Our typical QC procedure:

1. Super Coiled Fraction Measurement: >80% as measured by densitometry analysis on agarose gel



2. Endotoxin Level Assay: measured by LAL method: <0.1 EU/µg



3.Genomic DNA Contamination: measured by qPCR assay: <3%



4.RNA Contamination: measured by ribogreen assay: <3%

5.Protein Contamination: measured by micro BCA assay: <0.1%
