TBEV - RSSEV - FD
Tick-borne encephalitis virus, strain RSSE (Far eastern subspecies) original isolate. This Tick-borne encephalitis virus[RSSE] is preserved under Freeze Dried (-20C).Tests for the presence of mycoplasmae were negative. To confirm its identity the virus has been partly sequenced.
Product Risk Group:
Infectivity tested and quantified
Infectivity was proven by plaque titration. Infectious titre was determined to be 5x 10^7 PFU/ml.
Production cell line:
Passaged 6 times on suckling mice in 1993 and stored freeze-dried. New stock prepared by one passage on Vero E6 cells on 11th August 2011.
RT-PCR followed by sequencing of the amplified product.
We recommend to grow the virus on VeroE6 cells cultivated in MEM Eagle with Earle"s BSS (BioWhittaker, 12-136F). Following additives should be added to 500 ml of medium: 5ml Nonesential amino acids (Biochrom AG, K0293), 5 ml Sodium Pyruvate 100mM, (Biochrom AG, L0473), 5 ml L-Alanyl-L-glutamine 200mM (Biochrom AG, K0302), 5 ml Penicilin/ Streptomycin/ Amphotericin (BioWhittaker 17-745E), 25 ml FBS heat inact.s.American (Invitrogen, 10108-165). Multiplicity of infection (MOI) of 0,1 can be used for the infection and the infectious medium can be harvested 8 days after infection.
