Life’s too short to miniprep a clone you’re just going to throw away. 🗑️
What if you knew which clones were correct before you ever reached for a miniprep kit?
With Plasmidsaurus ZeroPrep Colony Sequencing, you can send colonies or liquid cultures instead of purified DNA and lasmid sequence back overnight. And because it’s amplification-free, there’s no bias to hide any mutations you’re trying to catch 👀
Our latest blog post covers three ways to fit ZeroPrep into your week, from skipping unnecessary minipreps to verifying clones the same afternoon at select local dropboxes. 👇

Most uncertain genetic test results get untangled one variant at a time. This team tested thousands at once (@calhoujd, @CGBiar).
Tuberous sclerosis complex (TSC) is a genetic disorder that can cause benign tumors in the brain, kidneys, skin, and other organs. Genetic testing rity, but more than 90% of TSC2 missense variants in the ClinVar database are uncertain or have conflicting classifications.
In a new Nature Communications paper, Biar, Wang, Camp et al. (2026) measured protein abundance for almost 9,000 TSC2 variants and mTOR pathway activity for 391. Pairing the two assays paid off: some variants disabled TSC2 without changing how much protein the cell made, so an abundance-only test would have missed them. In a clinical cohort, the combined data helped reclassify 212 of 276 variants of uncertain significance.
The team used Plasmidsaurus Whole Plasmid Sequencing to verify their prime editing guide RNA vectors and libraries, and Amplicon Sequencing to screen guides for editing efficiency before scaling up. As co-first author Carina Biar put it, the speed and affordability made the pilot experiments “not only feasible but approachable.”

When we say sample to discovery, this is what we mean.
We send back results you can act on: volcano plots and pathway enrichment for RNA-Seq, species-level breakdowns for microbiome samples, annotated plasmid maps, and alignments that point you straight to the mismatch.

There's no good time to discover your plasmid is wrong, but finding out months into a project is the worst. 👀
Did you know Addgene's QC team reports finding errors in about 30% of deposited plasmids? Not every error will compromise a construct, but an unexpected one can mean oubleshooting.
Fortunately, Plasmidsaurus Whole Plasmid Sequencing can help you catch issues before they derail your project.
But when should you actually sequence your whole plasmid? Our latest blog post breaks down four key moments when it makes all the difference. 👇

What does the future of protein design look like?
We recently sat down with @PetrSkopintsev and @isabelesain from the @DoudnaJennifer Lab, who walked us through their new Science paper on engineering compact RNA-guided nucleases.
In Part 2 of our interview, they take us through he cryo-EM structure of their AI-designed RNA-guided nuclease for the first time.
When a low-abundance contaminant complicated their variant screening, Plasmidsaurus Whole Plasmid Sequencing with ZeroPrep helped them quickly find the source and keep their project moving.
From there, the conversation turns to what's next: faster protein engineering, new functions, personalized medicine, and favorite dinosaurs 👀
Watch Part 2 now!

Delivery is one of the biggest bottlenecks in CRISPR: even a great enzyme is limited if it's too large to get where it needs to go.
We interviewed @PetrSkopintsev and @isabelesain from the @DoudnaJennifer Lab, who walked us through their new Science paper on engineering compact long the way, Plasmidsaurus helped keep their variant screening moving at a fast pace.
If AI models are advanced enough to predict protein structure, can they also help design complex enzymes from the ground up in the future? Watch Part 1 now to find out!
Part 2 arrives tomorrow: the result that surprised them, and a very serious dinosaur debate 🦖

With its enormous claws, Therizinosaurus looked like a formidable predator. But this dinosaur was likely a herbivore, a reminder that appearances don’t always tell the whole story.
The same can be true for cell cultures.
Mycoplasma can alter cell signaling and gene expression changes in the culture. Everything may look fine while unwanted contamination affects the biology you’re trying to measure.
Your RNA-Seq data can help uncover what isn’t visible. Plasmidsaurus now includes mycoplasma screening with all RNA-Seq results. We analyze non-host reads and screen for nine mycoplasma and related species, looking for strong evidence of contamination.
No extra sample or additional sequencing, just more insight from data you’re already generating.

Is your HEK293 really HEK293?
Cell line misidentification is more common than you might think. The International Cell Line Authentication Committee estimates the worldwide average incidence of misidentified cell line use at 22%.
Now every Plasmidsaurus RNA-Seq order checks for ready captured in your RNA-Seq reads to confirm sample identity, so there's no separate assay and no extra sequencing step.
With this approach, Plasmidsaurus can:
- Compare human samples against 917 cataloged cell lines
- Flag potential mixtures when a second measured cell line accounts for 10% or more of reads
- Assign mouse samples to 45 strain background groups
