Hantaan virus was purified from a microcarrier culture of Vero E6 cells by ultrafiltration and density gradient centrifugation. Viral infection was inactivated by treatment of the viral stock with(More)
The mouse mammary tumor virus-7 superantigen (vSAG7) is proteolytically processed in B cells at as many as three positions.

To determine(More)
