A known sample, so you can trust the unknown ones.
Lyophilized Exosomes are stable, extensively characterized biological particles — positive controls and calibration standards derived from traceable human cell lines. Reconstitute, measure, and benchmark your instrument against a value you can rely on, with no cold chain required.
Reproducibility starts with a known.
NTA gives absolute, calibration-free numbers — but to trust those numbers over time, across operators, and between sites, you need a stable sample of known properties to measure against. A well-characterized EV standard is that anchor: it tells you whether a shift in your data is real biology or instrument drift.
Because these exosomes are lyophilized, each vial is shelf-stable and ships without cold-chain logistics — the same lot can benchmark an instrument today and a year from now.
Reliable references for reliable results.
Our Lyophilized Exosomes provide a stable, traceable reference for your NTA measurements. Each lot is extensively characterized, giving you confidence in your daily assay performance and longitudinal tracking.
Validate instrument performance
Run the standard repeatedly and plot each result against its certified value. Points inside the ±2σ band mean the instrument is in control; a systematic shift pushes them toward — and past — the limits, flagging drift before it reaches your real samples.
Introduce instrument bias and watch the control chart respond. A reliable standard turns an invisible drift into a visible, catchable signal.
One standard, four jobs.
