摘要:
This invention includes a peptide comprising the sequence CAFRQVC and an antigenic composition using the same. It also includes an in vitro method of detecting HIV-1 and HIV-2 antibodies in a sample using the peptide, and a kit for carrying out the method.
摘要:
The molecular cloning and characterization of a novel human immunodeficiency virus type 2 (HIV-2), designated HIV-2.sub.ROD, is described. A recombinant .lambda. phage genomic library was screened with an HIV-2-specific probe to identify overlapping subgenomic clones. Fragments of these .lambda. phage clones were subcloned into a suitable vector to reconstitute the complete HIV-2.sub.ROD genome. The complete nucleotide sequence of this proviral clone was ascertained and the following genes and gene products identified: gag (including p16, p26, and p12), pol, vif, vpr, vpx, env, tat, rev, and nef. These gene products will be useful, inter alia, in in vitro diagnostic methods and kits for the detection of HIV-2-specific antisera.
摘要:
A method for diagnosing an HIV-2 (LAV-II) infection and a kit containing reagents for the same is disclosed. These reagents include cDNA probes which are capable of hybridizing to at least a portion of the genome of HIV-2. In one embodiment, the DNA probes are capable of hybridizing to the entire genome of HIV-2. These reagents also include polypeptides encoded by some of these DNA sequences.

摘要:
The invention relates to a new class of retroviruses, designated by HIV-2, of which samples have been deposited to the ECACC under numbers 87.01.1001 and 87.01.1002 and to the NCIB under numbers 12.398 and 12.399.It relates also to antigens capable to be obtained from this virus, particularly proteins p12, p16, p26 and gp140. These various antigens can be used for the diagnosis of the disease, especially by contacting these antigens with a serum of a patient submitted to the diagnosis.It relates to immunogenic compositions containing more particularly the glycoprotein gp140. Finally it concerns nucleotidic sequences, which can be used especially as hydridization probes, derived from the RNA of HIV-2.
