Blazars are the most active extragalactic gamma-ray sources. They show sporadic bursts of activity, lasting from hours to months. In this work we present 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 estimated the Duty Cycle (DC): fraction of time that the source spends in an active state. 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 the sample of selected blazars in the ten years of data. This analysis constrains a possible counterpart of sub-PeV neutrino emission during the quiescent states, leaving the possibility to explain the observed IceCube signal during the flaring states.
