Blazars, being highly variable sources across the electromagnetic spectrum, may serve as promising targets for high-energy neutrino detection, especially during flaring activity. The nearby blazar Mrk 421 provides a unique testbed using unprecedented multi-wavelength data during a 13-day flaring period to create a detailed model of the hadronic interactions. From that, connections of the neutrino spectrum above TeV energies with gamma-rays can be deduced, resulting in predictions of the neutrino event rate observable by cubic kilometre neutrino observatories. Within the data available, IceCube reaches sensitivities low enough to test the hadronic emission model of Mrk 421. We report about the modelling of Mrk 421 and implications for observations with the IceCube Neutrino Observatory.
