Blazars are the most active extragalactic gamma-ray sources. They showsporadic bursts of activity, lasting from hours to months. In this work wepresent a 10-year analysis of a sample of bright sources detected by Fermi-LAT(100 MeV - 300 GeV). Using 2-week binned lightcurves (LC) we estimatedthe Duty Cycle (DC): fraction of time that the source spends in an activestate. The objects present different DC values, with an average of 22.74%and 23.08% when considering (and not) the Extragalactic Background Light( EBL). Additionally we study the so called ?blazar sequence? trend for thesample of selected blazars in the ten years of data. This analysis constrains apossible counterpart of sub-PeV neutrino emission during the quiescent states,leaving the possibility to explain the observed IceCube signal during the flaringstates.
