Put some plasmids in the dropbox at 3pm yesterday and got the results at 02:55am. Less than 12 hours for the full annotated sequence of 4 plasmids is quite mind boggling

Sequencing a 165kbp BAC containing large repeats with @plasmidsaurus. I feel more confident than ever on what I have. What an amazing technology

I routinely sequence plasmids over 15kbp and pay a flat $15 with @plasmidsaurus for whole plasmid sequencing. Results next day!

The time, money, and energy @plasmidsaurus saves shaves somewhere between 2 and 5 days off of every one of our design-build-test cycles.

Shoutout to @plasmidsaurus for not only sequencing my 12 samples in less than a day but also being able to identify stuff like entire plasmid duplications!

Whole Plasmid Sequencing
Sanger Sequencing
Coverage
Sequences entire individual plasmid molecules with continuous long reads, ensuring completeness and structural accuracy
Returns only ~500-1000 quality bases per reaction, dependent on and biased by primer annealing, causing problems to be missed
Problem Detection
Detects mutations, rearrangements, and duplications across the entire molecule
Misses low-abundance mutations, structural issues, and entire regions not specifically targeted by a primer
Timing
Delivers results overnight
Often takes several days
Data Quantity
Data produced by each molecular species is distinct and reflects its proportion in the sample
Signal is the average of all molecules in the sample, so mixtures produce muddled results
Primers
Primers not required
Needs primers

I can get whole plasmids sequenced overnight by Plasmidsaurus for $15, and I don't have to faf around with primers. Considering what even one error in plasmid construction tends to cost in terms of time and resources, it's hard to think of an excuse not to fully sequence every plasmid you're using. This is not an ad; I was just gobsmacked.

And I have to tell you, working with Plasmidsaurus was fantastic. I shipped a colonized plate to them and within two days, I had a full high-quality 32.5 Mb genome waiting for me to analyze. They went above and beyond, running foundational omics pipelines—base calling, assembly, BUSCO analysis—and even provided visualizations I didn’t expect.

I've been doing molecular cloning for nearly 15 years now. I cannot state enough how much easier the validation process is with whole plasmid sequencing with Plasmidsaurus.

Before whole-plasmid sequencing, we knew our plasmids had issues but we couldn’t see them. It has allowed us to identify issue with vectors and avoid costly integration of these vectors into experiments and cloning workflows.

Plasmidsaurus has become a vital tool for me in terms of completely upending the way that I approach cloning. Whenever I pull a plasmid from glycerol stocks, I always check that it is what we think it is, and this can be a game changer rather than sinking days or weeks into the wrong thing.
