ViaComp®

ViaComp^® viability controls are advanced 2‑in‑1 synthetic cell mimics engineered to closely reproduce dead‑cell staining behavior in flow cytometry. They provide reliable, cell‑like performance for both spectral and conventional flow cytometry unmixing and compensation workflows.

How ViaComp^® viability controls work

ViaComp^® viability controls are designed to emulate the staining characteristics of real cells by binding DNA‑intercalating dyes, such as 7‑aminoactinomycin D (7‑AAD) and propidium iodide (PI), as well as amine‑reactive viability dyes. Each drop delivers a pre‑mixed suspension of positive and negative control particles that generate distinct, well‑resolved fluorescence peaks, supporting confident separation of live and dead cell populations.

Consistent performance for flow cytometry workflows

Because they are fully synthetic rather than biological, ViaComp^® viability controls offer stable, reproducible behavior across different users, instruments and runs. The ready‑to‑use dropper format integrates easily into existing spectral and conventional flow cytometry protocols, helping standardize unmixing and compensation without the variability, fragility or preparation steps associated with cell‑based controls.

Application and intended use

ViaComp^® viability controls have been verified and validated on analytical flow cytometers, making them a robust choice for laboratories that require dependable viability reference materials. They are intended for research use only.
