Abstract: Macromolecules such as nucleic acids, proteins, lipids or polysaccharides are aligned on a support surface by passing the macromolecules through a meniscus of a solvent containing the macromolecules. The meniscus may be that of a solvent between two surfaces at an interface of the solvent with air. One end of a macromolecule is attached to one surface which may be a glass surface and another end is free. The meniscus is moved relative to the surface to which the end is attached such as by evaporating the solvent or by moving the surface. As the macromolecule passes through the meniscus, the macromolecule aligns on the surface perpendicular to the meniscus. This method may be used in assaying, measuring intramolecular distance and/or separating of macromolecules.

Abstract: The invention concerns a composition useful for the manufacture of vaccines containing particles having the immunogenic properties characteristic of the antigen HBsAg, these particles being more particularly characterized by the fact that the particles equally contain a receptor for polymerized human albumin. They are obtained by transformation of human or animal cells by a vector containing a DNA sequence coding for the S and pre-S regions of a genome of viral hepatitis B, this DNA sequence being placed under the direct control of a promoter permitting the effective transcription of the sequence in the human or animal cells transformable by the vector.

Abstract: 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.

Abstract: The present invention relates to the isolation of a new gene, des, which encodes a M. tuberculosis protein named DES. The des gene appears to be conserved among different Mycobacteria species. The amino acid sequence of the DES protein contains two sets of motifs that are characteristic of the active sites of enzymes from the class II diiron-oxo protein family. Among this family of proteins, DES shares significant homology with soluble stearoyl-ACP desaturases. DES is a highly antigenic protein, which is recognized by human sera from patients infected with M. tuberculosis and M. leprae but not by sera from tuberculous cattle. Thus, the DES protein provides a useful tool for the serodiagnostic analysis of tuberculosis.
