Abstract

ABSTRACT We have developed a human herpesvirus 8 (HHV-8) 50% tissue culture infective dose (TCID 50 ) assay using the T1H6-DC-SIGN cell line. Infection of T1H6-DC-SIGN cells with HHV-8 induces expression of β-galactosidase, which was used to determine TCID 50 levels. Validation of TCID 50 values was performed by immunofluorescence assay of HHV-8 infection of immature dendritic cells at various TCID 50 doses.
