NA activities of NA-VLPs co-expressed with different levels of HA.H1N1-VLPs with different HA levels were collected from 293 T cells transfected with various DNA plasmids ratio and were normalized by the activities in NA-Star assays. (A) FLAG-tagged HA and NA protein levels (80 and 75 kDa) of the normalized VLPs were determined by western blotting using anti-FLAG monoclonal antibody. (B) Desialylation of fetuin by the VLPs was determined in ELLA. Mean absorbance at 492 nm is plotted against sample.
