A new PCR technology that’s unbelievably real.
Single molecule isolation changes everything for PCR.






Results ready when you are.
Analysis is the hidden bottleneck in most PCR workflows. Drawing manual thresholds, gating scatter plots, double-checking replicates — it's slow, subjective, and error-prone. Countable PCR doesn't require any of that.
Single molecule isolation without microfluidics
Every Countable PCR reaction begins with 30 million picoliter-sized compartments, forming a gel-like matrix inside a PCR tube with a simple centrifugation step. This massive partitioning reliably isolates up to 1 million target molecules, allowing each molecule to be amplified separately for precise and highly accurate results.
Unbiased amplification
Each molecule is amplified in isolation, eliminating cross-talk, PCR bias, and signal interference. The result — cleaner data and dramatically easier assay development than legacy PCR platforms. And it’s all done in a standard thermal cycler, no special hardware required.
Counting in 3D
The Countable system uses laser-based lightsheets to clearly distinguish each fluorophore, giving you crisp, high-resolution multiplex signals.  It rapidly scans your entire reaction – directly in the PCR tube – in less than a minute.  No bleedthrough, no sample loss, just clear and reliable results every time.

With ~30M compartments, we’re seeing significantly higher sensitivity with fewer reactions in our oncology assays and new opportunities have opened up in the fields of NIPT and infectious disease.
Reimagine what PCR will do for you.
By isolating and amplifying single molecules without bias, Countable PCR unlocks a new class of assays that go beyond what qPCR or dPCR support.
Detect rare events in the presence of high-abundance background — with sensitivity down to 0.004%, enabling applications like minimal residual disease, pathogen detection, and low-level mosaicism.
Confirm co-occurrence of targets or integration sites on the same DNA molecule — no amplification bias, no statistical inference. Â
Accurately quantify amplicons >150 bp, beyond the reach of qPCR or dPCR — ideal for gene integration confirmation, structural variants, and fusion detection.
Retrieve intact PCR products post-run for downstream workflows like NGS, cloning, or amplicon size validation.
Quickly combine targets without probe rebalancing, signal bleedthrough, or months of optimization — multiplex panels made simple.
