FAQ

Can you detect different wavelengths on the Fluidity One?

We only use one type of dye, o-phthaldialdehyde (OPA), for our latent labelling of protein samples running through the Fluidity One. OPA is excited at 365 nm and emits at 440 nm so these are the only wavelengths that the Fluidity One is able to use. However, our next instrument, the Fluidity One-W, will provide excitation and emission wavelengths for working with pre-labelled fluorescent proteins, biomolecules or polymers.

Please contact us to discuss your requirements for using Microfluidic Diffusional Sizing in combination with fluorescence.
