The present invention relates to Human Immunodeficiency Virus-1 (HIV-1) Group P of the strain designated 06CMU14788 and fragments thereof, primers which are derived from HIV-1 Group P, immunogenic regions thereof, immunoassays and nucleic acid based assays for the detection of Human Immunodeficiency Virus (HIV) that employ said HIV-1 Group P or fragments thereof and therapeutic compositions containing said HIV-1 Group P or fragments thereof.

Human immunodeficiency virus and uses thereof

Isolated HIV-1 Group O env polypeptides obtained from the HIV-1 isolate HAM112 are claimed, as well as (a) antigen constructs comprising fusions of one or more of each of HIV-1 Group O env polypeptides and HIV-1 Group M env polypeptide and (b) further antigen constructs containing additional Group O sequences and especially the gp41 IDR of isolate HAM112. Also claimed are polynucleotide sequences encoding the above, expression vectors comprising the same, host cells transformed thereby, and immunoassay methods and kits utilizing the antigen constructs of the invention.

Antigen constructs useful in the detection and differentiation of antibodies to HIV

A method of performing a rapid assay for the simultaneous detection and differentiation of the analytes HIV-1 group M. HIV-1 group O and HIV-2 utilizing a sequence specific polypeptide of each analyte as capture reagents. An analytical. device also is provided for performing the method which includes these capture reagents. Also provided is a test kit which includes the analytical device which further can include a positive and negative control.

Rapid assay for simultaneous detection and differentiation of antibodies

This invention relates to genetically engineered enzymes, their ligand conjugates, their manufacture, and their use in qualitative or quantitative assays. A hybrid enzyme, such as an AP-epitope, has a foreign amino acid moiety (an epitope) inserted near the active site of the starting AP enzyme. The foreign amino acid moiety binds with an analyte, and, as a consequence of this binding, the enzymatic activity of the hybrid enzyme, AP-epitope, is modified. The changes in the enzymatic activity are dependent upon the presence, or the amount, of the analyte. In another embodiment, the hybrid enzyme consists of a cysteine introduced near the active site of an AP to give a hybrid enzyme. The cysteine on the hybrid enzyme serves as a point of conjugation of a ligand, such as theophylline, ferritin, thyroxine, or digoxigenin, to form the hybrid enzyme-ligand conjugate. The ligand binds with an antibody, an analyte or a binding molecule to an analyte and as a result of this binding, the enzymatic activity of the hybrid enzyme-ligand conjugate is modified or modulated.
