Hi,

Has anybody tried a Brilliant Violet 421 secondary antibody in a typical
expansion microscopy protocol? I would be grateful if you could share
your opinions. As you know, some fluorochromes fade substantially during
the expansion process.

Also, using widefield microscopy in the DAPI channel*, we see a lot of
background (especially nuclei**) in negative controls (no DAPI). Anybody
has observed something similar?

*DAPI channel is 387/11 ex; Semrock DA/FI/TR/Cy5 4 band dichroic, 440/40 em.

** primary neurons grown on poly-lysine coated 5 coverslips.

Javier
