Powassan virus prototype strain LB. The virus is freeze-dried. Tests for the presence of mycoplasmae were negative. To confirm its identity the complete coding sequence of the virus has been determined.
Expression plasmids for the production of flaviviruses NS5 full length (MTase and RdRp domains). Synthetic gene optimized for E. coli. Coding sequence fused at its 5' with a cleavage 6His tag coding sequence
