Research Article Cites Viraffinity™ in Study of Viral Encephalitis

MONMOUTH JUNCTION, N.J. - Sept. 14, 2022 - PRLog -- Biotech Support Group reports on a new research article describing the simplicity and efficiency of their virus enrichment technology for Sindbis virus (SINV) expressed in cell culture. The citation is:

Yeh, Jane X., et al. "Treatment of Sindbis Virus-Infected Neurons with Antibody to E2 Alters Synthesis of Complete and nsP1-Expressing Defective Viral RNAs (https://journals.asm.org/doi/pdf/10.1128/mbio.02221-22)." Mbio (2022): e02221-22.

Alphaviruses are important causes of viral encephalomyelitis without approved treatments or vaccines. Antibody to the Sindbis virus (SINV) E2 glycoprotein is required for immune-mediated noncytolytic virus clearance from neurons. The investigation used direct RNA nanopore sequencing to evaluate how anti-E2 antibody affects SINV replication at the RNA level. The article states "Extracellular virus particles were isolated from cell culture supernatant fluids … using the Viraffinity virus and viral component isolation kit (BSG). For Viraffinity, virus-containing medium was added at a 4:1 ratio to the water-insoluble elastomeric polyelectrolyte and then microcentrifuged. (Viraffinity™-enriched) Virus pellets were directly lysed with TRIzol reagent….".  The study concludes that antibody-treated neurons released a lower proportion of SINV particles with capped genomes necessary for translation and infection.

"This report demonstrates that Viraffinity™ can substitute for the gold-standard of enrichment using gradient ultracentrifugation. However, the Viraffinity™ method is so simple, it can be applied using a conventional microfuge, and the viral nucleic acids can be directly isolated from the viral pellet. I am very pleased that by using Viraffinity™, the research was able to better understand virus clearance from neurons." states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
