Figure 2From: Label-free quantitative proteomics reveals regulation of interferon-induced protein with tetratricopeptide repeats 3 (IFIT3) and 5'-3'-exoribonuclease 2 (XRN2) during respiratory syncytial virus infectionLabel-free profiling workflow. RSV infected and uninfected HEp2 cells were lysed and proteins were separated by isoelectric focussing using offgel fractionation. Following tryptic digestion, purified peptides were characterized by UPLC-MSE and subsequent relative quantitative expression profiling.Back to article page
