Description: This virus is a chimeric alphavirus containing the non-structural proteins of Sindbis virus (SINV) strain TR339 and the structural proteins from Venezuelan equine encephalitis virus (VEEV) strain Trinidad donkey (TrD). Additionally, this virus expresses the reporter protein EGFP at very high levels with a minimal effect on viral replication or virulence. This product allows the study of VEEV TrD in a non Select Agent BSL-2 laboratory setting.
Strain History: TR339 is the consensus wild-type strain of SINV derived from the prototype AR339 isolate (Culex spp. mosquitoes, Egypt, 1952). The genomic sequence is available in NCBI. VEEV Type IAB strain Trinidad donkey (TrD) was isolated from the brain tissue of an infected donkey in Trinidad in 1943. The genomic sequence is available in NCBI.
Passage History:
- SINV TR339: Mosquito and suckling mice (unknown), CEF (unknown), BHK (unknown). References (1), (2) and (3).
- VEEV TrD: Guinea pigs (1), Vero (6), BHK (1). Reference (1).
Production: Transfection of In-Vitro Transcribed viral genomic RNA into Baby Hamster Kidney (BHK) cells. No serial passages performed.
Biosafety Level: 2
Titer: At least 1x10^7 PFU/mL on BHK cells. For lot titer, see the Certificate of Analysis below.
Format: Clarified and filtered cell culture supernatant frozen at -80°C. Delivered on dry ice.
QA/QC:
- Titer in PFU/mL by plaque assay
- Genome copy number/mL by qPCR
- Whole-genome sequencing by NGS
- Mycoplasma test by PCR
- Sterility test for bacterial contamination
- Endotoxin test <10 EU/mL
- Documented expression of EGFP reporter protein
- Documentation: Cell culture growth and passage, experimental conditions for QC tests, documentation of all reagents used.
Reporter virus construction: Reporter protein coding sequences were inserted between the capsid and PE2 loci and contain the 2A-like protease sequence from the Thosea asigna virus (TaV site) at the 3’ end. Upon polyprotein translation in infected cells, the capsid autoprotease domain and the TaV protease cleave the reporter protein from the capsid, resulting in reporter expression independent of incorporation into the virus particle.
