    摘要: The invention provides vaccination protocols for administering immunogens to a primate host in order to promote the formation of neutralizing antibodies (NAbs) against primate immunodeficiency viruses. In some embodiments, the vaccination protocols comprise the step of administering to a primate host a first immunogen comprising at least one primate immunodeficiency virus Envelope (env) sequence having a first set of consensus glycosylation sequences, followed by a second immunogen comprising at least one primate immunodeficiency virus env sequence having a second set of consensus glycosylation sequences, wherein the differences between the first set of consensus glycosylation sequences and the second set of consensus glycosylation sequences comprise differences in consensus glycosylation sequences observed in HIV isolates obtained at different time points of a natural infection.

    摘要: A method for purifying recombinant HIV gp120 so as to provide a glycopeptide having protein/protein binding properties substantially identical to natural viral HIV gp120, which comprises fractionating a composition containing crude gp120 sequentially using (1) ion exchange chromatography, (2) hydrophobic-interaction chromatography, and (3) size exclusion filtration, collecting at each step a fraction that exhibits specific binding affinity for CD4 peptide. The process is carried out in the absence of any affinity purification steps or any steps (such as reverse-phase HPLC) that use contact protein with organic solvents. The product obtained by this method is a purified, full-length, non-fusion recombinant HIV gp120 glycoprotein having protein/protein-interaction properties substantially identical to gp120 as presented on an HIV virus, including binding affinity for CD4 and binding affinity for at least one antibody capable of neutralizing HIV infectivity.

    摘要: Improved expression of tPA in mammalian cells is achieved employing a promoter region functional in a mammalian cell with a DNA sequence coding for tPA, where the sequence is interrupted by at least one intron. Particularly, a viral promoter is employed in conjunction with a hybrid gene having portions of the coding sequence uninterrupted by introns as compared to the wild-type gene and coding sequences interrupted by introns or the wild-type gene or mutants thereof.Plasmid pSV7tPA2I was deposited on Feb. 14, 1985 and given A.T.C.C. Accession No. 40163.
