 AB    Binding of human immunodeficiency virus type 1 (HIV-1) to membrane of
       its target cells was studied by a quantitative and non-isotopic method
       called the viral membrane trapping method (VMTM). Membranes prepared
       from the CD4 positive lymphoblastoid cell line CEM and adsorbed to a
       solid support retained the ability to bind HIV-1. Similar results were
       obtained by Western dot blot and ELISA modification of VMTM, when
       membrane fraction was bound to nitrocellulose or polystyrene,
       respectively. In ELISA modification, viral association with 1 microgram
       of membranes coated on 96-well microplate was linear within a range of
       3.75 micrograms to 60 micrograms of p24gag protein. The use of anti-CD4
       mAbs, OKT4A and 13B8.2, identified CD4 molecule as a major HIV-1 binding
       component of membrane fraction. The procedure will allow the study of
       virus binding to this and to other possible additional receptor(s).
