Figure 4. Western blot of purified His-tagged recombinant VP1 polypeptide of PLV-CHN with serum samples from healthy children and adults.

Figure 4

Immmunoreactive protein bands with the expected size of recombinant PLV-CHN VP1 (∼30 kDa) were detected with sera from both an immunized mouse (lane 1) and OD450 ≥0.355 (Lane 2, 3, 4, 5, 6 and 7), OD450 ≤0.305 serum samples were negative (lanes 8 and 9).
