Example of precipitation of biotinylated AviTag recombinant proteins with streptavidin beads
Figure4. 293T cells were transfected with different combinations of AviTag expression plasmids and biotin ligase, as indicated in the figure. Lysates were prepared 24 hours after transfection and incubated with streptavidin beads for 8 hours. Suspensions were centrifuged and pelleted beads were washed 3 times. Cell lysates (L), supernatants (S) and pelleted biotinylated protein bound to streptavidin beads (B) were resolved by SDS-PAGE. Biotinylated proteins were visualized on a western blot with streptavidin-HRP conjugate and chemiluminescent substrate (Pierce).
