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.
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.
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.
Confirm instrument performance across multiple sites and timepoints with a common reference.
