Characterization of HA-pseudotyped KAN-1 wildtype PRPs.
a) FACS analysis of eGFP expression in A549 cells untransduced (left) or transduced (right) with wildtype HA/NA/M/eGFP pseudotyped retroviral particles. b) Electron microscopic images of wildtype H5N1 PRPs produced from 293T cells. A free immature PRP (left panel), as well as a mature PRP (right panel) are marked by an arrow. An electron lucent core characterizes the immature particle on the left panel, whereas the more mature particle on the right panel has an electron dense core.
