Brighter secondary antibodies

Fluorophores are in constant development.

There is now a new generation of Alexa Fluor fluorophores: the Alexa Fluor Plus. They can be purchased already coupled to secondary antibodies on the ThermoFisher website.

Brilliant violet antibodies are also very bright and despite their name, they come in all colours. The can be purchased from Biolegend which produces the fluorophore.

Another excellent source of bright fluorophores is the Janelia Fluor dyes. They can be purchased coupled to antibodies from the NovusBio website.
