We will tell you when sequencing is the wrong tool
A study that cannot answer its question is worse than no study, and it is cheaper to find that out at the scoping call than at the report.
About
A lab that shows
its working
23rd Pair Lab Limited exists because too much genomic analysis arrives as a conclusion with no way to check it.
Who we are
The name is the method
The 23rd pair is a reminder that biological information is both deeply personal and incredibly complex. Understanding it takes more than simply generating data — it takes careful analysis, transparent methods, and confidence in how an interpretation was reached.
We are a team of scientists and bioinformaticians working to make life-science data more useful, accessible and trustworthy.
We develop computational approaches for analysing complex biological datasets, from genomics and metagenomics to microbial profiling, antimicrobial resistance and beyond. Our focus is on turning raw sequencing data into clear, reproducible and meaningful biological insight.
We believe better science comes from better tools: workflows that are rigorous, transparent and designed around the people using them. Whether supporting research, developing new analytical methods or solving practical bioinformatics challenges, our aim is simple — to help life-science teams get more value from their data and make better-informed discoveries.

How the pieces fit
Services, software and our own products
Three of our four offerings come from the same place: work we do often enough that it became worth building properly.
Services
Analysis we run for you, and pipelines we build for your team to own and keep. This is where most projects start.
Software
23rdExon, CAN and MetaXplore began as tools we needed for our own analysis work. They are independent of each other, and licensed for teams who would rather run the work in house.
NanoAmp™ kits
Our own targeted amplification assays for long-read sequencing, developed in-house and supplied for research use.
The common thread
Whichever route you take, the methods, parameters and quality metrics are written down and handed over.
Start with what you need: analysis and pipelines
How we work
Four commitments
You get the files, not just the summary
BAMs, VCFs, intermediate outputs and pipeline configuration. If you want to re-run our analysis yourself or hand it to someone else, you can.
Uncertainty is written down
Variants of uncertain significance stay uncertain in our reports. We do not round an ambiguous finding up into a clean answer.
A named analyst, not a ticketing queue
One person who knows your project, whom you can email directly, and who will still answer after the report has been delivered.
Tell us what you are trying to find out.
Send the question rather than the specification. If we are not the right lab for it, we would rather say that early and point you somewhere better.
