Types of Service

Plasmid Preps

Retrogen’s Plasmid preparation services move your research forward with robust workflows, quick turnarounds and as always, Retrogen’s highest quality of support. No need to buy a plasmid preparation kit when Retrogen’s plasmid preparation service provides the right kit for the scale you need and we do the work for you. Just submit your samples and we’ll return the purified plasmids, and can even guarantee a specific yield if desired.

DNA: You can provide competent cells or choose from our available strains

Glycerol Stock: Submit 200 µL of stock

Bacterial Colony: Provide colonies within 3 days of plating


Mini, Midi and Maxi-prep kits provided for your project

Quick turnaround

Online Ordering

Multiple available QC methods available to meet your needs

Direct Colony Sequencing

Utilizing rolling circle amplification (RCA), an isothermal amplification reaction where no plasmid prep is needed and a concatemers containing tens to hundreds of tandem repeats is formed to allow sanger sequencing. This method is proven effective across multiple sample types, including low-copy plasmids, circular DNA in supernatants, bacterial colonies and glycerol stocks.

Sample Types

Circular DNA: 50 µL of supernatant

Glycerol Stock: 1.5 ml tubes or 96-well plates shipped on dry ice (denote media type)

Bacterial Colony: Circle and number colonies to be sequenced (If no numbering, colonies will be picked at random).

Phage Plaques: Circle and number plaques to be sequenced


Flexible sample inputs

Quick turnaround time

Analysis on ABI 3730xl

Long reads (>500bp at or above Q20)

Universal primers at no extra charge

Online ordering and data retrieval

Gene Expression

Retrogen offers leading technologies for both NGS and qPCR-based gene expression studies. ThermoFisher’s OpenArray platform provides pre-made panels for ease of use and little to no development time for your project. Just select your targets and submit your samples for Retrogen to process. Pre-designed panels are available for human, mouse rat and many other model organisms. And you can’t find exactly the panel you need, Retrogen can help you develop a custom panel.

Sample Types

RNA: Between 0.002 and 0.2 µg/µL minimum input into cDNA synthesis reaction. Please ship on dry ice

cDNA: 1 ng to 100 ng cDNA into each qPCR reaction


Predesigned panels

High throughput

Microbial Identification

Retrogen can help with your bacterial and fungal identification needs using industry-standard 16S rRNA gene sequencing and Internal Transcribed Spacer (ITS) sequencing. Utilizing primers that amplify these highly conserved regions, these sequencing tools allow construction of phylogenies for identification of your micro-organisms of interest.

Sample Types

Direct colony sequencing: Plates or pellets acceptable

Glycerol stocks: Please submit at least 200 µL stock

gDNA: Submit 50 ng of gDNA in Tris or H2O pH 8.0


High quality assays to amplify 16S rRNA and ITS regions
