Wa. Scott et al., EVALUATION OF AN INFECTIVITY STANDARD FOR REAL-TIME QUALITY-CONTROL OF HUMAN-IMMUNODEFICIENCY-VIRUS TYPE-1 QUANTITATIVE MICROCOCULTURE ASSAYS, Journal of clinical microbiology, 34(9), 1996, pp. 2312-2315
Quantitative micrococulture assays of cryopreserved human immunodefici
ency virus type 1-infected cell suspensions and culture supernatants w
ere compared among seven assay sites. There was no significant change
in titer during 1 year of storage. The overall standard deviation for
infected cell suspensions was approximately 0.8 log(10) virus titer. A
method for detecting deviant assay results was developed and was used
to identify two donor cell preparations (n = 54) that gave consistent
ly low titers.
