Lyophilized Exosomes — 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.

Key facts: source-verified from traceable human cell lines; 4 characterized attributes (size, concentration, markers, morphology); no cold chain required (lyophilized stability); lot-to-lot batch consistency.

Why a reference standard — 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.

Benchmarking in action: run the standard repeatedly and plot each result against its certified value. Points inside the ±2-sigma band mean the instrument is in control; a systematic shift pushes them past the limits, flagging drift before it reaches your real samples.

What you get — one standard, several jobs

• Cross-site validation — confirm instrument performance across multiple sites and timepoints with a common reference.
• Assay reproducibility — build reproducibility into EV assays and diagnostic workflows from the start.
• Operator onboarding — a reliable standard for training lab staff and students on consistent technique.
• QC validation packages — support QC validation in pre-clinical and commercial pipelines.
• Tested every lot — each lot tested for size, concentration, protein markers, and morphology.
• Lyophilized format — long-term stability without cold-chain logistics.

Used across

• Extracellular vesicles — subpopulation tracking using CD9 / CD63 / CD81 markers.
• Virology — confirm viral capsid protein presence in particle populations.
• Nanomedicine — validate surface modifications of lipid or polymer nanoparticles.
• Method validation — anchor instrument qualification and stability studies.
