AB The risks associated with blood and blood products contaminated with
human immunodeficiency virus (HIV) has been an ongoing concern in the
health care industry. We tested the ability of a 0.04 micron nylon
membrane filter to remove human immunodeficiency virus (HIV) from fluid
containing serum and characterized the effect of filtration on the
concentration of serum proteins. The filters were tested with HIV
suspended in Dulbecco's modified minimum essential medium (DMEM)
containing 10% fetal bovine serum. Endpoint titrations of infectious
virus (ID50) were performed on lymphocyte cultures. Virus concentrations
were determined using an enzyme-linked immunoabsorbent assay (ELISA) of
the HIV-1 P24 core antigen. In three replicate challenges with 47-mm
membrane disks, no virus was detected in the filtrate. The titer
reduction was estimated to be greater than 8.5 x 10(2). The
concentration of IgM (900,000 Da), IgG (160,000 Da), and albumin (67,000
Da) in pooled human serum was determined by ELISA before and after 0.04
micron nylon membrane filtration. High recovery efficiency of these
proteins were observed. No relationship between the molecular weight of
the protein and recovery was detected. The results suggest that the pore
size distribution of the 0.04 micron membrane filter is sufficient to
allow biologically active serum proteins through during filtration.
