title: SMInput_nuc
design: Cells were infected with influenza A virus (WSN) at an MOI = 0.01 for 24hrs, subjected to UV cross linking with 254nm light, and fractionated to obtain cytoplasmic or nuclear fractions. NP was immunopurified and associated RNAs or size-matched input controls were processed with a modified version of eCLIP based on Van Nostrand 10.1038/nmeth.3810.
