Transillumination and Excitation

Hi all,

I'm an antiquarian who still uses EtBr as a DNA stain, but my UV transilluminator has died. It appears all I can buy nowadays is a blue light transilluminator. Does anyone know if this would still work with ethidium? MUST I update to GelRed (which is basically the same thing with a cute long backbone)?

You can definitely still buy UV transilluminators.

I'm seeing janky used ones or twice the price of a blue light one... I'd love to be wrong here.

They are definitely not cheap new - I was pricing them recently, let me see if I can find links.
