[Histonet] prediluted Fitc labelled antibodies?

I used to predilute the FITC conjugated antibodies and placed the aliquots in a -80ºC freezer until they were going to be used. In that way I could use them until the manufacturer's expiration date.

Hi all,

Has anyone experience with the shelflife of prediluted FITC-labelled
antibodies? We use them for direct Immunofluorescence and dilute usually
with PBS on the same day of use. With the increasing amount of IF-tests we
consider prediluting the antibodies. But I don't know, if there is any
negative influence.


Thanks in advance
